The brainchild of students from Arizona State University, this toilet has been designed with yoga principles in mind — and it's won its creators an award from the Northwest Design Invitational. Named Go with the Flo, the transparent blue loo has a sink built in above the cistern, allowing you to reuse the water you've washed your hands with when you flush.

There are no mechanical parts in the toilet: instead, an electromagnetic ball valve sluices just one-and-a-half gallons of water from the tanks to the bowl. So what, I hear you ask, has all this got to do with yoga? It's all to do with the position in which you find yourself, apparently. Squatting down builds and strengthens back and abdominal muscles, apparently.

While it may not be as beautiful as certain loos we've featured before — there's something redolent of a child's potty in the design. The only thing that confuses me is this: which way should one face?
