He's showing me how he wants to position an airborne hologram over the Dome of the Rock, a gold-capped shrine that's one of the most holy sites in Islam. "The blimp will go there," Hayutman says pointing into the blue. "And eventually the Messiah will come."

He has two big ideas, two ways to engineer the apocalypse. The first: a hovering holographic temple. Hayutman wants to set up an array of high-powered, water-cooled lasers and fire them into a transparent cube suspended beneath a blimp. The ephemeral, flickering image, he says, would fulfill an ancient, widely revered Jewish prophecy that the temple will descend from the heavens as a manifestation of light. Hayutman hopes to finance the project with some of the proceeds from a $20 million patent-infringement suit he and his partners have filed against Palm.

The rest of that money would be poured into Hayutman's second idea for jump-starting the end-times: a virtual temple within a massively multiplayer online role-playing game.
