I'm not sure whether these benches on the campus at Bath University look more like jaws or children's brick cubes... Admittedly they don't look very comfortable but I still rather like them.
Just behind St Martin's Church in London there's a spot where, if you get the timing right, you can sit and watch members of the Chinese community practice Tai Chi. You could even join in, and to be honest, these benches aren't the most comfortable!
