Paths made from sine waves

I stumbled upon this cool tweet here:

It's a way to draw shapes with just rotating vectors, or just basically sine waves.

Here's my initial test. It will scribble random pictures again and again. Nothing too interesting but I found it fun to watch.

Second go utilizing a user made path. Use the mouse to draw a new path while it runs.

The cool thing about this is it can be easily used to approximate a path with less data points and still be smooth.

At the very least it is entertaining and actually has a sketchy look to it.

Cool, sort of like lissajous.
