I don't see what everybody's problem with Slipknot is...lol. I quite like their songs. As to 'who they are' it doesn't really matter to me...as long as they make good music, I like it. Haven't been listening to them much, though...been listening to A LOT of Demon Hunter. I think they're on of my new fav bands xD.
Anyway, nice sig indeed. Don't really like how you positioned the stocks, but the effects on it are quite nice. I do a bit of PS work myself, but I haven't tried much of that...I'm more into doing rendering jobs (cutting out stocks from like wallpapers, etc). That and sprite animations, heh...
