File this in the “Wow, the World is a Small Place” category: I ran across this site the other day. It lists public Internet camera feeds from around the world and I thought it was pretty cool (these are only family-friendly camera feeds, so any pervs out there are going to have to get their fix elsewhere 😛 ).
Also cool, and my personal favorite, is the visual map showing the sun’s path across the planet. I think this is really amazing. It shows you who is in the dark right now. The Opentopia site is really great and there are many more cool things on the site so take a few minutes and poke around.
