A few of the games for Gnome use it, including the tetris game and the lights-out game.
Screenshots would be mostly useless, as most of the interesting stuff is zoom/fade effects that don't come off nicely in a screenshot, but if you search around for clutter tutorials you might see some crappy pics that don't show anything worthwhile. Better off just loading up something that uses it, that lights-out game is a pretty good example of what you can get done with a small amount of code -- and it's a good example of what all you can do with pure javascript in gnome, too.
(searching youtube for a screenshot? never heard of that before, interesting.)
