I thought some of you might be interested in watching a video (see link below) of Thomas Knoll, the co-developer of Photoshop. It's four years old, but still quite interesting, if you're able to spend 45 minutes on it.
I've also included a link to an interesting article about Knoll and his brother, John, who shared in the development and actually drove the project.
