A good analogy I've seen...at least the most easy to fake yourself into understanding.
Say you have a telephone wire, if you look at it from far away, it looks like it is a single dimension, now take an ant on that wire, it can revolve all the way around left and right, and can go backwards and forwards...2 dimensions, now cut it in half, and we get three.
Not very close to the dimensions the strings vibrate on, but an example showing that it's not always as it seems.
