Esper Dominoes topple without touching, we fall all over ourselves (video)

Quick, what's wrong with this picture? Oh, that's right -- dominoes don't topple all by themselves, do they? But these aren't your average tiles. Constructed by Japanese interaction researchers in 2009, these "Esper Dominoes" each have ZigBee radios inside, and as each stone falls it wirelessly tells the next to follow suit, all down the line. Of course, knowing all that, why would you ever settle for a boring row of five? Hit the break to see what these bones are really capable of, and join us in praying that some entrepreneur mass produces these perfect stocking stuffers before another two years fly by.
