If you've ever wondered what you might look like swinging from a building like Spider-Man, then head over to Dalston House in London, where you can make moves like the web-slinger himself without actually putting yourself in danger.
Dalston House is actually all an optical illusion created by Argentinean artist Leandro Erlich for the Beyond Barbican arts festival. Erlich took a vacant lot in East London, and built the facade of a typical house except that it was lying flat on the ground. Then he added a gigantic mirror set at a 45 degree angle over the whole thing, so that when you view it from the street it looks like just another house in the row. Visitors can crawl and climb around on the horizontal facade making their moves, but from the street it looks like they're making death-defying moves high up on the building.
If you happen to be in London and have a yen to unleash your own inner Spider Man, Dalston House will be open every day through August 4.
