To anyone wondering why on earth you'd want to build a paintball gun capable of firing 840 barrels' worth of ammo in 1/8th of a second, well, I bet you don't get why we went to the moon either.
The video above - wherein the massive paintillery explodes insta-graffiti onto a wall - was a marketing stunt sure. And fine, yes, the Mythbusters did it bigger and better. But seriously, is hundreds of paintballs flying in union and splattering up a work of art something you can ever have too much of? [Colossal via Laughing Squid]
