Terrorise tourists and amateur photographers with the "Image Fulgurator"
If you’re looking for a way of getting revenge on society without actually breaking any laws or getting yourself hurt, try this – it’s a way of projecting hidden text into other people’s photographs.
The “Image Fulgurator” uses a flash sensor to activate itself and beam your text onto walls, works of art and groups of innocent tourists at the exact moment someone’s shot is taken, so, hopefully, your target remains completely unaware you’ve just projected the word “tosspot” over the front of the Tate Modern in a superb piece of guerilla art that’d have “Banksy” going green with envy.
Two large bottles of lager + Image Fulgurator + public space = several hours of marginally evil but not actually illegal amusement.
