Sculpture: you can't get there from here

I'm a fan of mind boggling, whatever its roots. So, when I discovered this sculpture of a triple Klein bottle, I directed my attention its way. See, a Klein bottle is one of those impossible things that gets your mind rattled until it doesn't know what happened to it. It can't be created reasonably in three-dimensional space. Evidently, this British sculptor didn't know that, because he not only created ONE, he created one inside one inside one for a triple threat of 'em!
