MIT researchers have introduced a new way to bring ordinary objects to life with moving images, and it doesn’t involve electronics. The system, called FabObscura, helps users design and print barrier-grid animations, often known as scanimations, that give the illusion of motion when a patterned sheet is moved across an image.
The project, developed at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), lowers the difficulty of creating these effects. Instead of being limited to straight lines, the software allows users to explore a wide range of barrier patterns, from zigzags to spirals. According to lead researcher and PhD student Ticha Sethapakdi, the goal is to make it easier for people to design attention-grabbing animations for practical, creative, or decorative purposes.
Key Points
-
FabObscura enables custom barrier-grid animations without electronics, using standard 2D printers.
-
Users can input equations to generate unique barrier patterns beyond straight lines.
-
Supports nested animations, where two different sequences can appear on the same surface.
-
Applications include books, coasters, toys, packaging, signage, and artwork.
-
Trade-offs exist, such as reduced sharpness in multi-layered designs, but guidelines help improve clarity.
The system works by letting users upload a set of animation frames or select from preset sequences like a blinking eye. The software interlaces the images and produces a printable design that can be paired with a matching barrier grid. When the grid slides or rotates across the image, the picture animates. Researchers demonstrated this with several examples, including a coaster that shifts between a coffee cup, a martini glass, and water, as well as a jar lid that “blooms” with a sunflower when twisted.
Artists, educators, and product designers may find the tool especially useful. For instance, a children’s book could display simple cartoons, or packaging could animate when opened. The team also sees potential for dynamic signs in workplaces or construction sites.
Although current results are optimized for flat surfaces, the researchers are exploring ways to extend FabObscura into 3D printing and possibly allow direct video uploads for even more flexibility. Their findings will be presented at the ACM Symposium on User Interface Software and Technology (UIST) later this month.
In short, FabObscura turns static objects into interactive, animated displays that can capture attention in new and practical ways, bridging art, design, and technology without relying on power or screens.
