Well, after seeing the somewhat immature other paper replacement, I though it'd be fun to make some more.
VALVe, for the game, engine, and stuff. Not to forget the base paper thing (which I managed to salvage from the original paper).
Mike Myers, for the Austin Powers one.
Whoever made the other icons and I didn't credit (the "awesome" smilie, for example.).
Photoshop, an image maker which has definitely earned its stripes.
EDIT: Mr. Admin, I do believe there is an ingame screenshot, namely the 'banner'. Thank you.
