We all love and have fun with [satoshis.place]. Lets combine this idea with a Pixelflut LED display.
You dont know what a Pixelflut is ... take a look here: https://cccgoe.de/wiki/Pixelflut
It would be great to have a LED Matrix (like this one - but bigger is better), where there is an API Backend where I can buy pixels and with lightning to show at the next choas communication congress at the bitcoin assembly. So a first prototype is needed to get started.
Look at this LED tutorials: https://learn.adafruit.com/raspberry-pi-led-matrix-display
