Morphrig

Morphrig is an interactive manual in ten parts, about 71 minutes end to end, on how icon morphing really works, written by Sanyam. It starts from what a path is to a computer and works through correspondence, parking spare strokes, rotation, browser support and how to tell when a morph looks bad, with draggable shapes whose numbers come from the compiler that renders them. It suits design engineers who want to build icon morphs themselves rather than rely on a library.
