Welcome to the Fourth Dimension

Ready to have your mind bent? Here's an article on a statue of a four-dimensional object. It's warped a bit to work in the three-dimensional space we humans are able to wrap our brains around, something like how a cube gets distorted in a two-dimensional drawing, but most of the important parts are rendered true to form. I recommend the animated tour. It twists the brain just enough to make the whole thing work.
