You always knew there's an art to Rubik's Cubes, but it turns out there's more than you thought.
The street-art Space Invader folks, taking a break from surreptitious outdoor installations of vintage video-game mosaics, have branched out into using collections of Rubik's Cubes as an artistic medium.
They produced a number of simple Space Invaders mosaics, but more impressive are the larger photo mosaics--for example, the Clockwork Orange character made from a grid of 171 cubes. The phrase Stanley Rubikscubrik springs to mind.
Meanwhile, for traditionalists, there are new advances in the Rubik's Cube brain-teaser crowd. This Sudocube Sudoku cube puts a new twist on the idea.
