Okay, it might not be the fastest phone-cubing you've ever seen (or the funkiest,) but it's likely some of the shrewdest. Using an Ascend P6 at its heart, "MultiCuber 3" is the latest contraption from serial cube-coder (and ARM Engineer) David Gilday which combines Lego Mindstorms, algorithms and "because it's there" style optimism in equal measures. A custom app snaps the unsolved cube from all sides, to understand the starting point, then figures out the quickest path to color-coded harmony. Gilday claims that most human cubers would take about 120 moves to solve the 4 x 4 puzzle, making MultiCuber 3's 50 somewhat impressive. Watch the whole thing unfold in the video past the break, complete with appropriately euphoric soundtrack.
