  • Finally got around to building my cube and I'm pretty pleased with the way it turned out.I'm driving it directly from a Raspberry Pi - software available from Pi models work, even the $4 Pi Zero and with the interactive shell it's much more fun to interact with the cube in real-time and quickly develop new patterns or animations.
