There is one thing ive been super curious about ever since it made an appearance in the initial 2D release video, namely - how do you build complex curves like this:

I would love to know whats going on to the left of the angle converter node - i imagine there are several math nodes that i dont remotely understand. Ive had a lot of success riffing off of the XY Osilliscope example in wire, but I would love to be able to layer and modulate forms like that!
