The Internet is chock full of pictures. Surely somebody could do something interesting with them all.
Montage-a-google by Grant Robinson will take any search terms you enter and create a montage of the images Google returns.
Grant has also turned the concept around. Guess-the-google gives you a montage of pictures and you have to guess what the search term that generated them was.
WebCollage is even cleverer. It trawls the Internet and takes images at random then adds them to a constantly evolving collage. Clicking on any part of the collage takes you to the page where the image was sited. I originally found the site through a reference in my Site Counter. It kind of reminds me of the LiveJournal images page that had me hooked for a little while but better looking. Warning - The 'net contains a fair amount of pornographic images so the webcollage may be not be suitable for work or children
