I had to turn the depressing music off, but the video is awesome!
I was actually thinking about kite again the other day, and wondering if carbon fiber and foam could create semi-rigid kites that could do stuff flappy kites can't.
I tried flying my 808 camera on my Prism Stowaway Delta and the resulting video was nauseating to say the least.
A few of the kites in the video fly nice and stable, and seem to inflate like balloons.
I need to make something like that instead of a heavier kite.
