For those of you who missed it, we had the boards up and playing Tetris during Minne-Faire. Things were still a bit jury rigged then, but the core vision was realized.
And today today I got to place my order for a Raspberry Pi. So, in theory, in just 6 short weeks I'll have what I crave to finalize the design.
Jude has a plan to hang the boards behind the class room, so in theory we'll have a permanent installation fairly soon.
