Wow, this article is cool, but it loads a lot of shaders the more you scroll down the page, and unless you are on a very powerful computer, your browser might slow to a crawl.
FWIW my laptop from last year with integrated graphics had a conniption. Was barely able to see the animated gas giant picture and wasn't able to scroll past it due to the lagging page. I don't know if it's the graphics rendering or something else going on.
