Moo.fx is pretty slick. For a tiny little javascript library, moo.fx has monster potential. With what they are developing, you are only going to be limited by imagination and know-how to turn your static website into an online hard core app with real juice. If you check out the moo.fx forum at http://moofx.mad4milk.net/forum/ you’ll see a number of great looking real world examples, beta effects and a number of ideas in the hopper. My personal favorite? The accordion effect. It’s applicable to navigation, instantaneous interaction and site compression. Rock on moo.fx!
