Create random album covers - Time Waster
The formula is simple: choose to use either a random Wikipedia article or a simple adjective + noun for the name of your band, and a recent random photo from either Flickr or Photobucket. Currently album titles are pulled from quotationspage.com. Lastly, choose whether you want to create a "Metal" band album cover, the only effect of which appears to be adding umlauts over vowels randomly.
It takes only a few seconds to try, and you'll probably end up with a few good ones rather quickly. Here are a couple of my favorites: Spectral Mandible, Peoria Panorama, Puffy Jello, and Buddy Liles.
