I've scoured the rest of the internet, and I can't seem to find the screen saver I'm thinking of -- if memory serves, I last saw it about 15 years ago in grade-school on our Apple computers.
The screen saver was animated from a bird's-eye-view, flying over a 3D terrain composed colored dots (green dots for grass, blue for water, etc). The closest thing I can find that resembles what I'm talking about is a (still-image) here.
I've always remembered how cool I thought that was the first time I saw it, but I've never seen it since that day. Does anybody have any idea what I'm talking about/where I can find that screensaver?
