As an aside, having mandatory animations on slide transition as these, breaks one important functionality: the ability to speed through pages while seeing them briefly.<p>For example, on a powerpoint deck with animated slide transitions, when I’m presenting, a second hit on the right arrow key will kill the animation, so hitting the key repeatedly, although it makes me hit two times per slide, enables me to move quickly; whereas in this example, if I hit the key repeatedly, I don’t see anything readable.
