I think that for me, one of the most interesting distinctions with such a visual, design-forward experience is the line between what's possible with WebGL animation and what's really just high-production quality video playing in the background. Where most of us developers get stuck approaching this is that we don't have the video assets and design language established, so we see it as just a bunch of tools that you could theoretically put together to do... something arbitrary, and in the future. Whereas, if a design lead came to you with a strong design/brand and video content, it's really nice to know that the tools exist to make such a thing possible. You don't have to go crazy on the transitions and scroll jacking, either. Subtle use of these tools can produce humbling results.
