I remember in 1996, when I had just started my graduate work at UM, and I had a NeXTcube in my dorm room that I left on all the time (solid Unix there, thanks, the base for today's OSX yes that's right), and cats were pretty much the internet (except for MUDs and file depositories at universities).
Today, cats still rule. Amazing longevity. Behold my examples:
- Nyan Cat (currently at 31.8, even without the cool scrollbar that they made and nuked).
- Maru (with his own YouTube channel).
- What I am talking about! Kittywood Studios.
