During the keynote earlier this year by Steve Jobs, there was a demonstration on iChat effects which showed some great effects. However, a lot of them aren't in the release of Leopard I have! (i.e. the upside down effect), but especially the "mouth" effect they had, in which the mouth of the chatter becomes the mouth of a person's picture. Does anybody know where I can get this effect, or has it been left off the final release of Leopard?
