Photobooth Ideas

I need ideas for a photobooth to add to my wedding packages. Should I look for one pre-built or rig something up myself? I want it easy to set up as well. Any ideas?

camera high on a tripod, throw a big umbrella above it, and use a plain wall as the background. Pretty simple. If you want to go bigger, tether to a laptop so they can see themselves and have a remote release button so they can take pictures of themselves so nobody has to babysit it.
