I'm currently working through the Planet Earth series, which consists exclusively of jaw-dropping footage but jumps around a bit too much for my taste. If I had an HDTV, though, I'd probably be watching the series right now and deep into the night before eventually collapsing of exhaustion. On an HDTV, I can watch baseball for hours on end. Anyhow, Earth-Touch is another great resource for nature lovers that hosts short HD clips of all sorts of animals and environments. It's like having little windows into all parts of the world, but presumably less smelly.

On other planets, the most common plants could be red, blue, or even black. Think about it.
