Graphics Request (YouTube Banner)

[N.T.M.]

Hey guys, I'm not sure if this is the right place to post this, but I thought I'd give it a shot. I was going to start making some Stepmania-related videos on YouTube and I need a banner for my account. I'd do it myself, but I lost my Photoshop with the death of my last computer.

Just to give some background, one video idea I had was to make an in-depth tutorial on creating simfiles. I have a lot of experience with making simfiles, and I'm very well-versed in music theory, so I expect it to be high quality.

Here's the opening sequence I'll be using: http://www.youtube.com/watch?v=cLTinytWpIE

Because Stepmania isn't my only interest, I'd like the banner to portray other topics, too, namely piano, other video games (F-Zero, and maybe Super Mario), physics/math (maybe a few pictures of equations), chess, etc. Anyway, at least a few of those. I don't have anything particular in mind, so just be creative.

Lastly, please give yourself credit in the banner. That, or I'll give you credit in my account description.

Thanks, guys!

*edit* I'm not sure what the ideal dimensions are, but if you don't know, I'm sure it wouldn't be too difficult for me to find out.
