Michael sez, "While preparing the PK bunker for the December 21st Mayan Apocalypse, we made a startling discovery: a machine powerful enough to prevent the end of the world. Needless to say, we were excited. The only problem? The machine's only power source is donations to Public Knowledge. And, yes, we shot some video. We are so confident that this device will work that we offer you this UNCONDITIONAL GUARANTEE: if you donate to Public Knowledge before the Mayan Apocalypse, the world will not end on December 21st."
