Kick arse image gallery
Tutorialzine has an image gallery that really takes advantage of javascript and CSS3. Its very original and can be very useful. To put it simply its a pile of photos with real life functionality. The images themselves are each a fancybox link but thats not the cool part. You can grab each photo and move them around and pretty much chuck them anywhere you want even on top of each. As soon as you grab one it will come to the front.
The rotation of the images and shadows are done using CSS3 which is awesome but unfortunately it means it wont work in older and crappy browsers like IE and Firefox 2. The moving of the images is all done with javascript.
