Norris (who should have his own blog) writes about this really cool site in an email:
Came across this site today through WebZen. If it at all interests you, then be sure to play with the variations.

WebZen is at www.chaoskitty.com/webzen if you want to check out more net-based art projects.
And he adds in a followup email:
You might also check out www.uncontrol.com. There are a whole series of
little programs to interact with in interesting ways. I found some of them
to be very cool.
