Acorn

Theocacao: A Look at the Acorn Image Editor: “Acorn is first working example of what I would consider a programmer’s image editor. It has a very ‘objecty’ feel to it — sort of what might happen if Interface Builder was reincarnated as a bitmap tool. If you feel more at home in an IDE than Photoshop, I think you will probably like Acorn.”

Cool, I purchased Acorn a couple of months ago and now I know why.
