Tight Mode: Why Browsers Produce Different…
Researchers in MIT Professor Stefanie Mueller’s group have spent much of the last decade developing a variety of computing techniques aimed at reimagining how products and systems are designed. Much in the way that platforms like Instagram allow users to modify 2-D photographs with filters, Mueller imagines a world where we can do the same thing for a wide array of physical objects.
In a new open-access paper, her team at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) has demonstrated a novel printing technique along these lines — which they call “Thermochromorph” — that produces images that can change colors when heated up.
Led by first author and MIT electrical engineering and computer science doctoral student Ticha Melody Sethapakdi SM ’22, the researchers say that they could imagine their method being applied in ways that are both artistic and functional, like a coffee-cup that warns if the liquid is too hot, or packaging for medicines or perishable foods that could indicate if the product has been stored at a safe temperature.
So-called “thermochromic” materials that visually change with temperature are not new — you can see examples with consumer beverages like Coke and Coors Light that reveal “ready to drink” labeling when refrigerated. But such instances in product marketing have traditionally been limited to a single color. By using inks with complementary characteristics — with one set that goes from clear to colored, and another from colored to clear — Sethapakdi says that she and her colleagues are “finally taking advantage of full-color process printing, which opens up a lot of possibilities for designing with thermochromic materials.”
The researchers worked with several visual artists to teach them to use Thermochromorph, and then solicited feedback and brainstorming about new narrative concepts and techniques unlocked by the tool, like color-changing postcards that could tell sequential stories in more compact, dynamic ways. One participant even plans to use Thermochromorph to make an educational science kit aimed at teaching students about sea creatures that change color.
The team developed their method to be applied specifically to “relief printing,” an early form of printmaking that involves carving a design into a block of material, applying ink or pigment to it, and then transferring the image onto paper or another surface.
Sethapakdi says that, compared to techniques like screen printing, relief printing is “more lightweight” and can be done with less setup and fewer materials, enabling a faster, lower-stakes iteration process. Artists that include the likes of Pablo Picasso and Salvador Dalí have used a range of related approaches in their work, such as woodcut and linocut printing.
“Our key contribution is applying these new materials to a traditional artistic process, and exploring how artists might be able to use it as part of their practice,” says Sethapakdi, lead author on a related paper that was recently presented at SIGGRAPH Asia in Tokyo.
The color-changing component also need not come from an active external heating or cooling source like, say, a fridge or a hot plate; using thermochromic inks with lower activation temperatures can allow for more subtle thermal changes brought about by human touch. Sethapakdi says she could even imagine applying this new process to create interactive surfaces or dynamic analog “interfaces” that visually change in response to touch.
Thermochromorph combines digital and analog processes in the form of, on the one hand, CMYK imaging and laser cutting, and, on the other, manual printmaking and thermochromic inks. Fabrication involves four core steps:
The three prints the team used to demonstrate their technique were a set of frames from a Batman comic, a label depicting a fish and its underlying skeleton, and an image of a male subject both in profile and viewed from the front. (For the latter, as the temperature changes, the viewpoint gradually shifts, giving the effect of motion.)
It’s worth noting that Thermochromorph does have some potential limitations related to image resolution and print quality. Specifically, image resolution is constrained by the smallest dot size that the team’s laser cutter can engrave. Techniques like screen printing would offset this, but with the additional drawback of needing more time and materials. In terms of print quality, the pigments are not entirely invisible in their ‘clear’ states, which means that the clarity of the transitions depends on how thickly the ink layers were applied during printmaking. While this issue is intrinsic to the properties of the pigments, Sethapakdi says that for future iterations the team plans to explore different image-processing techniques to modify the overlay of halftone patterns for the hot and cold images, which may help to reduce these visual artifacts.
Sethapakdi and Mueller co-authored the new paper alongside Juliana Covarrubias ’24, MIT graduate student in media arts and sciences Paris Myers, University of California at Berkeley PhD student Tianyu Yu, and Adobe Research Scientist Mackenzie Leake.

2024 is coming to an end, so let’s take a look back at my tutorial videos from the past year and see which topics proved to be the most popular. Once again my Neon Light Effect Photoshop Tutorial from back in 2021 continues to dominate my YouTube Analytics as my best performing video, now with 2.8 million total views. Sadly, none of my uploads this year have managed to pull out any extraordinary numbers, my best performing videos are just about on par with 9th and 10th place from my 2023 roundup! I thought my recent Vaporwave Neon Effect Photoshop Tutorial might have followed in the footsteps of that popular Neon Light Effect tutorial with it being the same process with a different result, but the stats aren’t quite living up to expectations yet with 3000 views so far. Hopefully this will be one to watch if the algorithm decides to shine some light on it in 2025.

On an otherwise dark and rainy Monday night, attendees packed Kresge Auditorium for a lively and colorful celebration of student product designs, as part of the final presentations for MIT’s popular class 2.009 (Product Engineering Processes).
With “Balance!” as its theme, the vibrant show attracted hundreds of attendees along with thousands more who tuned in online to see students pitch their products.
The presentations were the culmination of a semester’s worth of work in which six student teams were challenged to design, build, and draft a business plan for a product, in a process meant to emulate what engineers experience as part of a design team at a product development firm.
“This semester, we pushed the six teams to step outside of their comfort zones and find equilibrium between creativity and technical rigor, all as they embarked on a product engineering process journey,” said 2.009 lecturer Josh Wiesman.
Trying to find a balance
The course, known on campus as “two-double-oh-nine,” marks a colorful end to the fall semester on campus. Each team, named after a different color, was given mentors, access to makerspaces, and a budget of $7,500 to turn their ideas into working products. In the process, they learned about creativity, product design, and teamwork.
Various on-stage demonstrations and videos alluded to this year’s theme, from balance beam walks to scooter and skateboard rides.
“Balance is a word that can be used to describe stability, steadiness, symmetry, even fairness or impartiality,” said Professor Peko Hosoi, who co-instructed the class with Wiesman this semester. “Balance is something we all strive for, but we rarely stop to reflect on. Tonight, we invite you to reflect on balance and to celebrate the energy and creativity of each student and team.”
Safety first
The student products spanned industries and sectors. The Red Team developed a respirator for wildland firefighters, who work to prevent and control forest fires by building “fire lines.” Over the course of long days in challenging terrain, these firefighters use hand tools and chainsaws to create fire barriers by digging trenches, clearing vegetation, and other work based on soil and weather conditions. The team’s respirator is designed to comfortably rest on a user’s face and includes a battery-powered air filter the size of a large water bottle that can fit inside a backpack.
The mask includes a filter and a valve for exhalations, with a hose that connects to the blower unit. Team members said their system provides effective respiratory protection against airborne particles and organic vapors as users’ work. Each unit costs $40 to make, and the team plans to license the product to manufacturers, who can sell directly to fire departments and governments.
The Purple Team presented Contact, a crash-detection system designed to enhance safety for young bicycle riders. The device combines hardware and smart algorithms to detect accidents and alert parents or guardians. The system includes features like a head-sensing algorithm to minimize false alerts, plus a crash-detection algorithm that uses acceleration data to calculate injury severity. The compact device is splashproof and dustproof, includes Wi-Fi/LTE connectivity, and can run for a week on a single charge. With a retail price of $75 based on initial production of 5,000 units, the team plans to market the product to schools and outdoor youth groups, aiming to give young riders more independence while keeping them safe.
On ergonomics and rehabilitation
The Yellow Team presented an innovative device for knee rehabilitation. Their prototype is an adjustable, wearable device that monitors patients’ seated exercises in real-time. The data is processed by a mobile app and shared with the patient’s physical therapist, enabling tailored feedback and adjustments. The app also encourages patients to exercise each day, tracks range of motion, and gives therapists a quick overview of each patient’s progress. The product aims to improve recovery outcomes for postsurgery patients or those undergoing rehabilitation for knee-related injuries.
The Blue Team, meanwhile, presented Band-It, an ergonomic tool designed to address the issue of wrist pain among lobstermen. With their research showing that among the 20,000 lobstermen in North America, 1 in 3 suffer from wrist pain, the team developed a durable and simple-to-use banding tool. The product would retail for $50, with a manufacturing cost of $10.50, and includes a licensing model with 10 percent royalties plus a $5,000 base licensing fee. The team emphasized three key features: ergonomic design, simplicity, and durability.
Underwater solutions
Some products were designed for the sea. The Pink Team presented MARLIN (Marine Augmented Reality Lens Imaging Network), a system designed to help divers see more clearly underwater. The device integrates into diving masks and features a video projection system that improves visibility in murky or cloudy water conditions. The system creates a 3D-like view that helps divers better judge distances and depth, while also processing and improving the video feed in real-time to make it easier to see in poor conditions. The team included a hinged design that allows the system to be easily removed from the mask when needed.
The Green Team presented Neptune, an underwater communication device designed for beginner scuba divers. The system features six preprogrammed messages, including essential diving communications like “Ascend,” “Marine Life,” “Look at Me,” “Something’s Off,” “Air,” and “SOS.” The compact device has a range of 20 meters underwater, can operate at depths of up to 50 meters, and runs for six hours on a battery charge. Built with custom electronics to ensure clear and reliable communications underwater, Neptune is housed in a waterproof enclosure with an intuitive button interface. The communications systems will be sold to dive shops in packs of two for $800. The team plans to have dive shops rent the devices for $15 a dive.
“Product engineers of the future”
Throughout the night, spectators in Kresge cheered and waved colorful pompoms as teams demonstrated their prototypes and shared business plans. Teams pitched their products with videos, stories, and elaborate props.
In closing, Wiesman and Hosoi thanked the many people behind the scenes, from lab instructors and teaching assistants to those working to produce the night’s show. They also commended the students for embracing the rigorous and often chaotic coursework, all while striving for balance.
“This all started a mere 13 weeks ago with ideation, talking to people from all walks of life to understand their challenges and uncover problems and opportunities,” Hosoi said. “The class’s six phases of product design ultimately turned our students into product engineers of the future.”
