gawd, I'm such a geek. but this okgo video makes me smile. actually, parts make me laugh out loud. it's just so cleverly put together; a perfect mix of geeky, scienc-ie precision, and true art. watch it ... and then if you're like me, watch it a few more times to catch the bits that slipped by unnoticed. word is it was a shoestring budget kind of affair. and though it was clearly done in one take, I wonder just how many attempts were required to get there.
my brother's and my childhood marble-runs were never so cool.
