Groovik’s Cube

Speaking of big cubes, some people I know in Seattle are building the Groovik’s Cube, a 15' \times 15' \times 15' Rubik’s Cube, illuminated by 648 superbright computer controlled LEDs, to be assembled and installed at Burning Man this year. I think what they’re doing is technically impressive and really fun. (Next year, Barry, we’ll do a 7 \times 7 \times 7. No, wait, a five-dimensional cube.)
