Prototype a few uses of dynamic ink using Dan Amelang and Evelyn Eastmond’s Ploma as the renderer. There are lots of visual languages we could build from these objects and their relationships—e.g., a wire that has one of its ends inside a blob is an input to that blob, while a wire that has one of its ends just outside a blob is an output of that blob. …but not so good when I tried animating strokes.
