The tesseract is a theoretical mathematical object that "predicts" what the most simplest object would look like in the 4th dimension. In our third dimension we would call a tesseract a cube. But when we try to project this 4th dimensional object into our own 3 dimensions, we can only see it's "shadow." And it's shadow is mindbending.

Well there would be many other shapes in the 4th dimension, besides the tesseract. What would they look like? That we can never know, because as humans we do not have the ability to live in the 4th dimension. So anytime we try to imagine what things would look like in the 4th dimension, we are only seeing the "shadows" of those objects. Adrian Ocneanu, professor of mathematics at Penn State, has designed and created a sculpture so we could see the shadow of a new 4th dimensional shape represented in our 3 meager dimensions.
