Have you ever seen those websites where its one giant canvas, but you can only see a portion of it at any particular time, maybe the top left. than if you move your mouse to the bottom of the screen the canvas starts to slide so you can see the bottom part. so no matter where you move the mouse the canvas moves. until you get to the edge of course. If anyone has any examples I'd appareciate it. I have seen a few in the past, but can't find them for the life of me.
