What is needed is a nice and clean design, focusing on the Amiga in a retro or futuristic way. The site will still be quite 'shallow' since it'll only be a listing of what tracks are available - apart from the submission system - which means it shouldn't be too hard to do this. I'm very fluent in CSS + XHTML, so that won't give any fuzz, but if any of you feel up for helping out with the new design, please contact me here or via the contact form on the site itself.
There really are no guidelines other than the above mentioned so the design can pretty much be in any way you create it. Just think of it as a big listing of remixes + some additional links and info and it'll be just fine.

...and yes, I plan to make the site skinnable (which it actually is right now as well, but I don't use it) so more than one design can 'win' this.
When I get hold of something good as a prize, I'll make sure to give that to the winning entry.

Go ahead - design like the wind!
