Mind your step is a large scale 32 x 18 meters (105′ x 59′ feet) street illusion in Stockholm at Sergels torg made by me, Erik Johansson. It will be on the square between 7-12 June 2011. For a long time I have been doing creative retouch and surreal montages. I’ve always been quite fascinated by perspective illusions in my images and some time ago I got an idea of trying to realize one in a public space somewhere.
