Yo dawg, this guy heard you like playing games with your keyboard, so he put a game on his keyboard

Snakes on a Corsair

Mythic Maniac isn’t content with just a regular keyboard. Instead, he coded his Corsair K70 RGB to play Snake — that classic game that everyone played on their calculators in math class. It’s controlled by way of his keyboard, which then produces the actual snake and the objective by way of LEDs.

If you want you can grab the source code here, written in C# Net. Basically you load up the Corsair Utility program and run the executable, and you’re good to go.
