Imagining the 10th Dimension

I got an e-mail today, with a link to this site. Now, in order to "get this," you need a little background in Quantum Physics.
One of the most important "subatomic concept" is that of parallel universes. It is assumed that, far from there being one universe, there are infinite one. Each choice we make creates a "road not taken" universe, and all the exists in our present universe is what we see.
String theory is one of the ways physicists are attempting to order this reality with our everyday reality, where there only seems to be one universe. The effort is important for our understanding of why the subatomic universe seems to operate under a different set of "rules."
This site is a flash enabled graphic presentation of the 10 dimensions proposed in String Theory. Have a look - it's fascinating!
