Imagining the 10th Dimension: A Flash Movie

I just StumbledUpon this site on the book called Imagining the Tenth Dimension. First I really liked the idea of the 0-10 numbers in the helix format. Then when I clicked on 0, it took me to the next page explaining in a very nice and fun way, with lots of pictures and animation, about the 10 different dimensions out there. Definitely worth a vist, if you are slightly intreseted in string theory and astrophysics.WOW!!!
