Kicking myself for not bookmarking the thing, but a while back someone posted their portfolio and the landing page featured this very nice animation made up of some points and parallel lines. In the comments I remember they linked to a lesser known library that was creating the animation.
I've tried searching here and through Google but no joy so far, and I don't have much to go on (can't remember if it was canvas, SVG, fork of D3(??) etc)
Anyone who can point me in the right direction gets a beer on me next time they're in London
