This Art Project Bridge is Held up by Three Giant Helium Balloons

This art project bridge would be one of the most futuristic things I've ever seen if it were actually usable.

You could try to cross the bridge, but that would defeat the purpose of artist Olivier Grossetête's submission to the 2012 Tatton Park Biennial. The art project bridge " reflects the architecture of Tatton’s Japanese Garden as well as the flight of fancy of the Formal Gardens as a whole," according to the Tatton Park Biennial's blog.

It's probably a good thing that it's not actually a functional bridge, seeing as it ends straight into the middle of a pond. Still, in a world filled with suspension bridges, this is one heck of a clever way to suspend a bridge.
