Andy Geppert contacted me last year to integrate a 8x8 neon matrix to his incredible Core memory kit.
I sent him a matrix and he built adapters and code to integrate it. He sent me a complete kit, and it is amazing to play with! Here some details from Andy: https://hackaday.io/project/166155-core-64-interactive-core-memory-badge/log/187719-core-memory-neon-pixels
And his website is www.core64.io .
