Moving Scroll Bar Clock Makes My Inner Web Designer Queasy

On the surface, scroll clock looks like a simple visual trick: Look, it's a clock made out of moving scroll bars! This is a marginally clever animation! Then you realize that every one of them actually works.

It's been a looooong time since I've done anything resembling serious web design, so my initial reaction was an iframe-induced panic—what black magic is this, etc—but a quick View Source painted a neat, tidy picture of CSS and Javascript, working together to shatter our basic intuitions about How Things Move, on the internet.

And while it may be a decade late, this is the first truly compelling use for Windows' old Active Desktop feature I've ever seen. This one's for you, inexplicably extant Windows ME users. [Scroll ClockThanks, Marco!]
