From Pablo Curutchet's 30' statues of cardboard men to Banksy's keeled over and dead phone booths, these 14 cool art installations are both eye-catching and interactive in a way that few museum attractions could ever hope to be.

These installations are also fascinating because they can take so long to put together, but will often be removed from their original locations so quickly. In many cases, the creations will often be completely destroyed by the time they're taken apart. Some of these, like the Banksy piece, weren't even put up with permission—of course, that didn't stop people from trying to buy it.
