Oh hey, a new look!
All of the Unused Graphics pages have been given some manner of overhaul, from new content to simply streamlining things a bit.
Besides that, this is pretty much a straight port of the old site, so it's just as cluttered and disorganised as it's always been.

The walkthroughs have disappeared momentarily, but I aim to revamp them into a new format. Stay posted!
I'd like to broaden the scope of the site and make it more in-depth, but we'll just have to see what happens.
