Non-related, but this is the first time I actually like animations that happen while scrolling. I think it has something to do with the fact that I still have control over the scroll on the right.

Yes, this one doesn't hijack the scroll. It just reacts to it, by changing the text formatting.

I still didn't like it. But it's undeniably much better than the usual way people animate their sites.

Having tried out CodeHike, there are a number of configurations or situations where you can get into scrolling and alignment issues

I'd much rather see each individual graph as a picture so I can compare.
