Surfing around youtube, I found this quite interesting show, called the elegant universe, wich explains the general idea of einsteins general theory of relativity, quantom theory and string theory. It seems to be made for the average joe, so you might think it has be dumbed down too much, but it will be still a nice watch. Beware that thinking in more than 4 spacial dimensions may cause self-implosion in the fifth dimension.

I'd advise to at least skip parts: 1, 7, 8, 9, first part of 14, and probably more, read the comments to find how useful the part is.
