This digital clock forms four digits using blue-dyed water in small bottles instead of LEDs. Each digit has a 3-by-5 grid of fifteen bottles, for sixty in total. An initial design with a shared pump and valves suffered from leaks and air in the lines. The final mechanism uses a tiny pump for each bottle, then tips the bottles to empty them when the display needs refreshing.

Brux built a working miniature bowling alley inspired by Wii Sports. Three lanes reset their own pins and return the balls. The lanes can also feature walls, ramps and a loop-the-loop. Gears and linkages power the mechanism, with many parts 3D-printed.

Matthew Lim made objects from flat materials using kirigami cuts and folds, including a phone grip and a table. The table uses plywood and 3D-printed hinges to lock into different shapes.

An exhibit at NT Tokyo 2026 featured a 'half-human pen plotter,' a drawing machine that deliberately leaves part of the work to a person.

The small XY stage moves the paper while a human presses a pen down and lifts it up. The drawing itself is difficult to see while working, but the user can feel the paper moving through the pen and hear the mechanism.
