Jodi.org is a art project. JO and DI are the abbreviation of the artist. The original entry to the site was 23.org (now sends you to hackers) which was a strange pyramid. I remember they got their start or had galleries at Art center college of design - Pasadena.
It was called Net.Art. I was also really big designing it, kind of like hacking before it was big. You made code do things that it shouldn't, make the browser shake or many pop ups that close themselves...all big feats back then. You will never get the full effect of these sites now becouse of how the browsers block most of the code. Back in the day when you pulled these sites up they were just moving. Even one time the guys from JODI made a game that downloaded in pices onto your desktop... now that would be called maleware.
Hell.com (I was a member) was a site that basically was a gallery of all net artist and a place to cloab and they gave you a email addy. They did work like organizing Radioheads crazy OK computer website. Idiots Hell.com are as they were offered 18 million in the late 90's for that domain but they turned it down due to pride. Bet they are kicking themselves now...lol
I personally single handedly destroyed the only Net.art listserver of the net art groups by photoshopped porn and txt bombs, was a anarchist back then now work for the united nations... funny how things turn around.
Lots of Net.Artist went into hacking and web development.
