Looks very cool, I'd like to help here with you too. I like the idea of those randomizers/logic gates. Sounds really nice, and now I really want TPT to have a recording option in a way..
For your concern about wifi, it has up to 99 channels, each channel 100 temperatures apart, so I bet you would have enough.
Convo me, if you'd like me to help you also.
Seems good, i can help with something like display if you want =D
I see i can't use wifi =D
But what kind of display? To show the image of the snake? i can make it =d
