In his book, Imagining the Tenth Dimension, Rob Bryanton explains - in plain English - the weirdness of string theory and the tenth dimensional (where all possibilities for everything are contained) physics using a clever Flash animation.
The beginning reminds me of the intriguing book Flatland [wiki], a 1884 book by Edwin Abbott.

I thought this animation was really interesting and clever.
I am so thankful for this website for explaining everything and in a way that the more ... simpler-minded folk (heh) can understand.
The thing that bothered me about the site is the "1 million unique visitors". Psuedo-scientists are always trying to pump up their numbers with claims about how many people agree with them.
