I've stumbled upon the IntelliJ site again recently and wondered - could you animate the stroke that they use in the background?

Maybe not exactly like the one in the picture, but some sort of way to alternate the draw width between different nodes of a path? I've spent quite some time now trying to ask Google in all sorts of ways what I'm trying to accomplish here, without much success.

Sure - I may be able to implement this through some intense clip-pathing and JS, but is there really no other way to achieve similar behavior? Or have I just simply not found the right words to pass to Google and SO so far?
