Web cams are old news. I remember how excited I was when I first played with slow scan TV and then with CUSeeMe. I stopped looking at web cams lately, because staring at a coffee pot got boring after awhile.
Kenji Eno just sent me a link to the Aizu Wakamatsu station web cam. Again, the content is not that interesting. It is just a train platform. However, the speed and the resolution are so high that you can see people walking and things flapping in the wind. You can hear the announcements and listen to the trains come and go. It's amazing how far we've come. I'm sorry if this "wow" is out of sync, but this web cam made me realize how far we've come.
UPDATE: I think it's getting a bit choppy as people hop on the stream. Be nice to their bandwidth please.
UPDATE 2: There is a steam locomotive (SL) that shows up sometimes.
