Core Animation + Photoshop/GIMP

So, I was thinking about the GIMP on leopard, and I thought about Core Animation and Core Animation being a layer-based animation system. What came to me was a very brilliant thought: Core Animation acellerated image editing. If I were designing this system I would use Core Graphics (specifically Core Image) to implement the layers. I find this interesting because one could then implement something like Cover Flow for the layers. The way I thought of it a user would press a button and then the layers would rearrange themselves into something like Cover Flow. I might do some mock-ups later, but for now it is just an idea.
