How does a ten-dimensional universe work?

I’d always wondered what physicists meant when they referred to a ten dimensional universe. I can really only understand four (length, depth, width, and time); any more than that seemed out of reach and absurd.

But this morning I found a neat flash animation entitled “Imagining the Tenth Dimension” that helped me get my head around the concept. It’s pretty interesting stuff.
