As impressive pieces of technology go, this one rates a "gotta show it on the blog" even though it has nothing to do with LatAm, stocks, politics or economics. Watch this video (and thanks due to reader MR for the headsup) then when you're done, go and find out more about the way young way smart whizzo Zdenel Kalal, the dude behind Predator, on his page here.
Guaranteed to impress and to make you think of James Cameron movies, too.
