Sure, you could spend a while trying to solve the Rubik's Cube in Google's new Doodle, but that may get a little dry. Google was clearly prepared for that eventuality, though: it has just launched the Cube Lab, a Chrome experiment that lets you build your own internet-based puzzle. So long as you're good with modern web code, you can produce a unique Rubik's Cube with its own artwork, effects and even logic. The 808 Cube is all about music-making, for instance. Even if you're not a programmer, it's worth checking out the ready-made Lab examples to have some fun. We just wish we'd had this when we were kids -- it would have kept us playing with Rubik's Cubes long after the original got buried in the closet.
