Nim based Firmware -- it's tiny!

[PMunch]

Nim is a really good fit for micro-controller stuff. I participated in a game 
jam for the Arduboy earlier this year. It's basically an Arduino Leonardo with 
with some buttons and a black/white screen. Did a lot of nice trickery with 
macros and such to load BMP images on compile-time and turn them into an 
internal sprite format with some proper types to make the drawing functions 
dead simple. Super cool stuff!
