Belgian artist Carsten Höller has installed a pair of tubular (both in the literal and figurative sense) spiral slides on the outside of the Hayward Gallery in London's South Bank. The slides look like so much fun, and also surprisingly nice aesthetically. In fact, we can't think of a single building that wouldn't benefit from a giant slide or two on its exterior. We've drawn up some highly professional renderings to help the world's architects get started.
Let's make it happen.
