average of 50 people's photos
This is one of the best things I've seen on flickr so far:
Since you can "tag" a photo on flickr with words that describe the image, you can search through other people's images based on their tags. This guy has done an average over 50 different people's photos for a bunch of tags: sunset, happy/sad, eiffel tower, a bunch more, and the four seasons, shown above. If you look closely, you can see that some people used horizontal shots, while others used vertical shots, and the average of the photos gets the colors just right.
If you're flickr-ing around, you should also check out some photos of Africa. Three guys that I know: 1 2 3 have all worked at the lab and are driving together 3500 miles from the UK to Gambia in a cheap/crappy car for fun and charity. You can see their route and sponsor them! I especially like it when they take pictures of the same thing and you can see the same subject from three perspectives...
