Ask HN: What's Paydirt using for its animated demo?

Leaving aside the the world vs IE storm that Paydirt kicked up, does anyone know if there's a toolkit/library for creating something like their animated demo on the homepage?

There's a thread on StackOverflow, anyone else have any clues. I'm not that keen to dig into canvas.
