To use: draw a simple ‘S’ shape on the left-hand panel. Then experiment. Note that it’s fairly crude and only renders convex surfaces properly.
This was a quick mockup I made at the end of last year to try out an idea for a Christmas Card. It was originally going to be for making baubels, and would have the addition of automatic smoothing, concave rendering and mapping a christmassy texture onto the surface. Probably saving, galleries etc. might have followed.
I like simple interactive toys like this, where you can understand what to do straight away and there’s an immediate reward and a sense of play.
