I remember seeing Photoshop, when it was pre-Adobe, in a hospital, in Ann Arbor.
I thought it was amazing.
One note: I'm almost certain that the version of MacApp (the Apple Pascal app framework) was still in beta, at the time.
I used some of Tom Knoll's code (a B-spline algorithm), as a base for a curve editor. He had done some work as a contractor for the company I worked at.
One of the tech people in the hospital was friends with Tom Knoll, and had it running on a Mac II (I think). I was taking a class there, and the teacher took us on a field trip, to see it.
