One of the most impressive moments of yesterday's Occupy Wall Street marches, was when someone projected a giant 99% "bat signal" on the side of one of lower Manhattan's skyscrapers as thousands of people swarmed across the nearby Brooklyn Bridge. New Yorkers know the Verizon Building as the windowless, concrete eyesore that looms over the bridge and mars the downtown skyline, so seeing it used is such a way certainly got a lot of attention.

But who did it? And how were they able to project the stories-high words on the building just as the protesters made their way over the span? Boing Boing's Xeni Jardin spoke to Mark Read, one of the Occupy Wall Street organizer who pulled together a team of friends and artists that arranged for the projection to happen.I

Read says he got help from two video projection artists, Max Nova and JR Skola, who used a 12,000 lumen projector and programmed the software needed to properly program the message. He also found an apartment in a nearby housing project from where they safely angle the projection on to the building. He says he offered to rent the apartment from a single mother of three, but when she found out what they wanted to use it for — and saw what happened during the eviction of Zuccotti Park — she refused to take their money.
