Ask HN: Alternative to PowerPoint with advanced animations and rich graphics

I 've been using PowerPoint for years and I used briefly Keynote, Prezi and other pieces of software but never found anything that can support complex animations and rich computer graphics. I often watch Bret Victor's software and I am jealous especially because I know there isn't anything out there that can do what he does. Or is there? Is there maybe a piece of kit that I am missing?

Anything you 've seen and tried is worth mentioning. Otherwise I think I will have to build this myself.
