Skip ahead to about the two minute mark in the above video to see an example of what the Image Fulgurator actually does. It’s basically a device that projects your favorite messages onto various surfaces when it detects flashes from nearby cameras. No tourist would be safe from your hilarious “Down with Pants!” message splashed across all their photos from the Basilica di Santa Maria.
It was designed by Julius von Bismarck and there’s a patent pending on the device. One possible downside is that it almost looks like a submachine gun, which might make it harder for merry pranksters to move about stealthily. Photos after the jump.
