Well, yes!
I have already done few gaming related folder icons (PlayStation, Pacman, Joystick, Nintendo DS) and I'll soon upload them, right now I'm too tired to pack them.
I'll deffinetly make some more icons, and not just gereric Max OS X Leopard folder icons. So stay tuned if you are interested.
Oh, and I you want some specific folder icon, just ask, if I'll find your idea worth doing, I'll deffinetly be happy to meke it.
For thoes who want to ask me why I'm making icons if I'm mostly video editor, so there's an answer:
I like to find things fast (yes, I use Spotlight a lot) so visual aid helps a lot. Ofcourse on Mac you can use color
