I saw an adafruit tutorial about this, though there hasn’t been much hype. I think might try to combine this with the leap motion.

I reached out to the developer and found that she has a few boards available.
I’ve ordered two of these. Now I need some Pixel matrices.
Build or buy ?
I have adafruit’s 8x8. It’s nice (still wishing they’d switch over to the WS2812Bs), but for $35 you can cut up a strip for way less.
