Even though it's a very basic website that looks like it's 10 years old, Pretty Planet is just too pretty to not mention today. It is a collection of earth images as viewed from space. My favorite is one that captures a sand storm blowing off the western coast of africa - I had no idea how far out sand is carried.
In other news: I just posted my third (and final) CHI2006 blog entry. It's a bit long and boring, but try to enjoy anyway. 🙂
