Incidentally, anyone who wants to see the cameras in action, there's an awp map for CS:S beta that has one in. Not too high quality, but the entity might be configurable, or it might just be my graphics card.
Next compo should be soon, as I've just gotta e-mail the results to atom. It'll be a few days before it's posted, but I'll tell the winner to think up the new compo before they're officially posted.
