That's exactly what I was aiming for! I always thought Turing Tumble was such a cool concept, by why not miniaturise it?

Funnily enough I'm currently building out a "Duplo" concept to make roons easier for kids. It's a disk with double-thickness bars (so a 4x4 grid instead of 8x8) but that loads directly onto the standard disk drive, so everything stays compatible. Still a WIP tho!
