Remember that video from a while back that demonstrated rudimentary multi-touch support on a G1that basically amounted to unreliable finger painting? Well, it's happened incrementally, but the tech has come a long way, baby. Videos have popped up here and there but this is by far the most impressive I've seen. And while Google has announced nothing, the footage below is pretty exciting. Is it just me or is the music exhausting after thirty seconds? Maybe I've just watched the video way too many times.
