With some coworkers we have been working on making a cabinet for the office
It is far from ready, but the concept is using “packing material” that they give away in wood stores. Normal designs use 18 or 22 mm mdf or such, but we are using those free 12 mm plates and there is no visible screws also! (also it is super slim… and uses discarded lcds and PCs. So it is like recycling!)
The wood was cut in a small office CNC (X-Carve) so it also required some alignment trickery to make it work.
It is far from ready, but eventually it could run some fullscreen arduboy games with a modded http://arduboy.ried.cl UI that launched the emulator on fullscreen… of course no coins required
