I was browsing some photography on www.deviantart.com and in a lot of the descriptions, it will tell you what kind of camera was used automatically and then sometimes the person will describe which filters they used, Photoshop, etc. Somehow I stumbled upon
this which can be used by a compact digital camera. And since Cokin makes small, square filters (the A series) I can use high quality filters without having a high end camera. I do plan to get a nice professional quality Canon one day but it's hard when you don't have any money for that. Anyway, I just thought that was really awesome because the filters aren't that expensive.
Here are the filters, if you're curious:
