It also doesn't animate text though. The content is all in place, with pretty animations and such in the background.

Not my preferred look, which is admittedly pretty spartan, but it works.

Edit: It does animate the code being typed. But that seems less critical to me then the main body. I would still prefer it to be static personally, but it works.

I believe stripe's designers include @destroytoday, his design of paper 53 impressed me a lot several years ago [1]. Surely it also contains animations, but it's more elegant and smoother.
