My current (pun!) obsession is a live stream (pun!) of Brooks Falls in Katmai National Park, Alaska, managed by a site called Explore.org. It's got good resolution and sound, which is rare for such a cam. It's so peaceful and calming to have it on a second screen, watching the bears and salmon and listening to the water rushing over the falls. They've got a bunch of other great streaming cameras as well, placed all over the world. Great way to explore the world from the comfort of your air-conditioned home.
