Some effect ideas

• Page index (display pages on an array or in a browsable fashion)
• Zoom and fade out... (zoom on the current slide while it fades out and shows the next one)
• Alpha animations (make an alpha channel on the difference between two slides to animate only the difference)

Please note this are only ideas (more ideas welcome, send them to mirko.maischberger(at)gmail.com). I'm planning to implement some in my spare time, but i'd like more if YOU'll implement them and send code to me ;).
