Couldn't these "Unique transitions" be applied to most existing slideshow plugins, since they are done with CSS3 and not the plugin itself?
Say, if I was using http://slidesjs.com/, I could do `addClass('animate-in')` using the `animationStart()` event.
I say this as I'd like more people to contribute to a solid, widely used and tested slideshow plugin, instead of adding another choice--of course this assumes that there's no need for another choice.
