Loved this. It's simply an amazing tool for building an intuition! I'll reuse it a lot.

One quick suggestion, partly to help answer Luka's question above: it may help to have a "sine generator". Maybe two sliders to create a single sine wave at different frequencies and phases. This would make it obvious that a wave at the right frequency "wraps around" and creates "constructive interference" that causes a vector to appear on the complex plane, but any other frequency causes "destructive interference" that cancels out.
