I always really enjoy this guy's videos. This one in particular is a great demo reel of what he's capable of - the creativity on display, combined with his knowledge of how flutes work, is such a joy to witness. He's extremely talented musically too - it's always fun to watch his compositions after his various experiments.

The guy just totally embodies the hacker spirit in a domain that many of us never touch (i.e. acoustic instruments). Really cool stuff.
