I guess some people are upset about Flickr video - I got an invite to an anti-video group just today. I didn't join. I'm going to love being able to upload short clips to Flickr - I think it'll encourage me to do more stop motion with my photos, which I love.
This is from 2007. It took 600+ photos to make this one minute, 19 second-long video. I love how you can see the leaves on the trees moving in the background.
