It's been quite a long time since I had a google maps-related post, but this is pretty cool.
TIMELAPSE
'Timelapse' is basically a google maps that cycles through time from 1984-2011, for any area you choose. So you can see environmental changes, urban growth around your hometown, or any other long-term trend you can think of that shows up on satellite imagery. There are some neat presets, but just searching around is interesting as well. For example, how did a giant lake just appear SW of Los Angeles in 2000? Chapel Hill/Durham really do seem to have grown. And watching Chernobyl grow back over is kind of neat.
