From the New Scientist Short Sharp Science blog:

A California conceptual artist claims he has "painstakingly decoded" alien artwork broadcast from deep space. Yes, you read that right.

"Concluding centuries of speculation about extraterrestrial intelligence, conceptual artist Jonathon Keats recently discovered that a radio signal detected by the Arecibo Observatory in Puerto Rico contains artwork broadcast from deep space," says the press release. ...

Keats' other pseudo-science works include customising the metric system and attempting to genetically engineer God in a Petri dish.

Also, don't miss his attempt to sell his own brain.
