That was simple one-page website with good transitions.

I didn't much like how the first graph built up while scrolling, iirc other sites normally make the graph static to the page while its built up during scroll. This one the graph was moving across my screen as it assembled, quite awkward.

No doubt it's simple, but it's attractive (probably largely thanks to the artwork). Not so great on my iPhone though.

And thanks, it looks like "one-page site" is what they're called.
