Hi everyone, I have always been fascinated by encryption and it's algorithms, so I was wondering if any one had any suggestions for getting started on writing my own.

Many interesting and useful links have already been suggested, but none of them directly answer your question. I would suggest Bruce Schneier's essay, So, You Want to be a Cryptographer. Basically, it says "study math; break codes." In particular, I direct your attention to the following:

Almost certainly you will get the urge to invent new cryptographic algorithms, and will believe that they are unbreakable. Don't resist the urge; this is one of the fun parts. But resist the belief; almost certainly your creations will be breakable, and almost certainly no one will spend the time breaking them for you. You can break them yourself as you get better.
