This proof-of-concept shows a coverflow effect using the new CSS transformation feature from Webkit (featured in Safari 3.1). Needless to say that it won't run in other browsers at this point (however, adapting it to canvas should be quite easy, and even now, it won't break in other browsers).
Unlike other demos, this one can truly animate between two half states, making a slider implementation like the iTunes slider really easy (will come to this demo soon!). Have fun and try using the keyboard for hotness ;)
