This is the unicorn of fancy websites because for once, it actually makes sense to override browser's standard scrolling behavior. The 30-minute timeline on the right provides an obvious context for what you're navigating with the scroll actions, and you wouldn't be able to do that with a regular scrollbar.
Usually scrolling overrides happen because the designers' mindset was that the site should be a sequence of beautiful slides. They might prototype it as a Keynote presentation that is approved by management. And then some poor web developer gets tasked with building a site that feels like the Keynote slide show that everyone loved, and the only way to do that is to turn scrolling into an annoying "next slide" action.
