Photoshop is celebrating 25 years of screwing with our perceptions of reality. Happy Birthday, Adobe, we'll never forgive you for that time you convinced us Bert and Ernie had gone totally badass.

Check out the video below, in which John Knoll, one of Photoshop's co-builders, recreates the first demo he ever gave with the software. And it only needed 2MB of RAM to run.
Tricks and blips.
