Scobleizer posted a casual 18-minute talk with John Knoll:
"John Knoll released Photoshop 20 years ago next month with his brother, Thomas. It changed the world of graphics and digital photography in a big way. Here's the full interview, done in a hallway of Lucasfilms' Industrial Light and Magic, where Knoll now works (he does special effects on films, including on Avatar)."
Update: not for AE info, but fxguide's January 15 podcast for which interviews John Knoll, who discusses of stereo 3D techniques and more.
