Programmable Ink Lab Notes

Deformation

Physical pen and paper tend to be a write-only medium. Sure, you can erase pencil, but it never goes back to the original blank slate. In a digital medium, you can cleanly undo or erase unwanted ink strokes, or select the ink to move it around on the page. But you can also go further, bending and reshaping the strokes of your pen. But how should digital ink behave when tugged and prodded? Does it act like a wire, holding its shape until forcefully kinked? Or like string that bends and twists but doesn’t stretch? Or elastic which can stretch but not squash? Should it feel like a “real” physical material, or is it okay if it acts like a spline or other purely virtual thing? And how should we implement this deformation so that it performs well, and can be programmed (or programmed with)?
