Fans of the xkcd webcomic have taken up the challenge laid out in one of the strips and are riding roller-coasters with glued-together chess-sets.
One of my all-time fave strips from xkcd is Chess Photo. The gag is that a prankster is gluing down his chess-pieces so that he can get on a roller-coaster, sit in the front seat, and be photographed deep in concentration over a gnarly chess-problem while behind him the rest of the coaster's riders go berserk.
Now xkcd fans are submitting photos of themselves doing just this (pictured here, "Jared Meadows and Renea Campbell at King's Dominion") -- including one incredible shot of an
Army Marine captain in full camou on a military helicopter.
