Webcollage is a program written by Jamie Zawinski that covers your computer desktop with randomly selected images from the web. The most fascinating part of it is that it gives you a feel for the proportions of things in the world. Obviously sex is extremely important and gets a lot of representation on the web. Pictures of people having (nonsexual) fun are also very common, such as parties, nightclubs, and just hanging out looking cool. Also, there are a lot of pictures of cars and buildings. Special groups are another common type of image like, for example, sports teams and music groups. Oh, yes, and people love to put pictures of their pets on the web.
