Very nice! I had a trig teacher years ago that taught only using formulas, without showing or explaining the unit circle. It was so confusing, hated the class until I discovered the unit circle diagram like this, then it all made much more sense.
That was my exact motivation while making this! This visualization helps me alot to understand trigonometry so i think it will be good to make a sandbox out of it. I hope this helps somebody who trying to understand basics of trigonometry.
