Here is a quick upload of all the numbers (0-9) built with only 3 points. Sorry about not animating them... didn't have time. https://www.youtube.com/watch?v=yddpzyQoy_0&feature=youtu.be

Nice. Seems unlikely we could get it down to 2 points as numerals like 3 seem to require two distinct curves, but perhaps someone will try?
