Heres a video of it in action, sorry if the formatting is poor. You can see a small error where the snake goes in the wrong direction briefly, I believe this is because the 256 Bytes of RAM slows my ticks per second to 60. I recently (after this video) updated, allowing me to use the pulse to a simpler byte and a near double in speed, I also replaced the dot display with an RGB.
Hope you enjoy, love the simulation and you videos!
