This is a clip from an old TV series, in which the astronomer, Carl Sagan, explains the concept of a 4th spacial dimension. He does so by first explaining what a 3rd dimension would be like for a 2D creature.
It's quite interesting stuff. Just thought I'd post it.

Haven't even watched it yet and I know it will be interesting. I love Carl Sagan.
