Was thinking about this again today, while talking to someone who was too young to have used orbit when it was new.
I also distinctly remember hanging out in the Noggin chat rooms around the same time.
I was a dork, see.
But I was trying to explain to a friend about how cool Cartoon Orbit was, and he looked at me like I had six heads.
So I think I have to add f/loss html5 public domain and Creative Commons cartoon orbit reboot to my project list.
