It looks like there's a CSS property that would make it moderately easy to implement as long as you make separate boxes. You would need to prepare a squiggly line box with transparent background to serve as the basis for your dynamic borders, and the rest would be a matter of defining background colors. The header box would have to be positioned on top of the other to hide its background. Hopefully the whole thing would port well to mobile views.

It's an interesting project, maybe I'll give it a shot tonight, but others should feel free to jump in in the meantime.
