This topic deserves a lot of attention, that is just an awesome idea.

Frances thanks that you shared it, there were so few live copy ideas or maybe just I did not perceive, but that is very interesting. Not even only for snowflakes, but a kind of next level of QuickShape tool and which can not customize more there, it can be done here.

I just jumped into it for some minutes, modifying just that simple triangle and so possible to add control points and playing with the negative space
