Animated SVG Logo

I've made this one based on gorgeous work by Eddie Lobanovskiy. I've used GSAP JavaScript library.

Unfortunately SVG do not support this kind of animation on shapes and it works only on strokes. On the other hand, strokes cannot have a variable width in SVG. To make this animation possible I've made characters and put a stroke behind each of them and masked strokes by characters :)
