I built a ridiculous 1000 pixel display that takes an hour to draw an image and I'm now asking the internet to draw on it (what could go wrong?) Please submit some 40×25 pixel art at kilopx.com!

This project has everything: a web app, a physical controller, a custom CNC build, generated gcode, tons of fabrication, 3d modeling, 3d printing, material sourcing - so much to get lost in. It's the most ambitious project I've ever built.

Picking pixels was a real adventure. I've tried ping pong balls, styrofoam balls, bouncy balls, wooden balls, 3d printed balls, golf balls, foam balls... The problems I encountered were largely cost (even a 50¢ ball is $500 of balls), weight (again, 1000 of these things), and availability.

I settled on wooden cubes, painted black on two faces, and turned by a little poking mechanism.

I built a whole CNC machine around the wooden cubes, and I can tell the machine to go to change a specific pixel. Just one at a time, of course.

This has been a real passion project for me for six years. It's nuts. I shouldn't have done it, but I did. So please reward me, and go play with it!
