Two 12x10 matrices, one on each face
Large USB battery, 20,000mAh lasts for two nights.
Teensy 3.2
~10 patterns
Can you tell us more about the matrix? How large is it, and what did you build it out of?
The WS2812B strips are arranged into a zig-zag pattern on a piece of cardboard, which sits in between two pieces of corrugated plastic sign board. It’s not that big, maybe 10 inches wide. That construction sits on top of a cardboard pole and is connected with USB cables to a small control box.
Unfortunately, I lost the construction pics.
Oh, I thought it was much larger. Good photo angle. 
Yea, this is like a fisherman holding their catch in front of them for the photo, I thought this thing was HUGE (like billboard size) based on the pic. Cool build tho still!
Hahaha… didn’t even think about the relative perspective of the shot, just glad it all came into focus. The cardboard tube is about 5 feet tall, with about 6 inches of sign on top, and here’s a pic with a quarter for scale.
I once made a sign THIS big!!

You made it, it worked, and others were able to enjoy it too. All awesomeness.
Plus you now have a sweet little desktop display!
