Hi,
I have done things with LEDs mainly and I was looking to see what ya'll have dreamed up. I have some ideas, I was just looking for more. Unfortunately right now it can't be a permanent thing as I only have one Rpi. I do have an 8 x 8 matrix I have been reading up on how to wire it. I was thinking about a roulette wheel. I know how it should work, but I am not up on Python code yet, so I will have to do some reading..
So post some of your creative things that you have done..
