Love a challenge? The Noops are inexplicable machines that don’t do anything at all. Pick one, make it do something, and have fun with code along the way.

All it does is emit a hex code. From #000000 to #FFFFFF—and all 16,777,216 colors between—you can do anything you want with the data. Show the color? Sure. Show the 80s movie poster with that hex as the dominant color? Better. We've got the documentation and few starter ideas in the repository.
