I modded an IKEA OBEGRÄNSAD lamp with my LED driver & custom firmware. It now displays 16bit grayscales @ 120 FPS.

@brainsmoke this is super awesome! Would you mind writing it up with some detail on how to reproduce this? Would love to build it for the upcoming mid-summer celebrations.

@dvim A bit late for this mid-summer, but I think I've written up most of the relevant stuff in the repo's readme.
