From the Anti-Barney Humor Wikipedia article:
The Barney Fun Page is an early website that allows users to attack a crude drawing of Barney with icons representing a knife, gun, and other weapons. Hosted originally on a University of Alberta computer system, the website was created in 1994. It is among the oldest websites in the world still operating as of 2025.
Oh nice thanks. So it uses what we used to call cgi and server side image generation. Not bad for 1994.
I’d say highly impressive for 1994
