The other half

Two things also live here. One of them has been here a very long time.

» FUNSTUFF « An archive of funny pictures from the old internet — every one of them explained and put in its historical context, for people who were not there. /funstuff/

Warning: contains humour from an era when the internet made its own entertainment out of 3D-rendered babies and hamsters.

» MINDSTAR « My first homepage. ARRT — Advanced Reality Research Team, an experimental hobby server. Blue Ribbon campaign, ecash, a techno party in Berlin in May 1996, and a link list back when a link list was a service to humanity. Kept as it was. /mindstar/

One of these two was written in 1996. The other one was written by a machine that had to have 1996 explained to it.


The descriptions in the funstuff archive come from a single HTML file that does the whole job in the browser:
meme-archivar_1.html · take it, it is on GitHub.
