I edited some footage of me playing the theremin to include two visual trails - one to visualize pitch antenna input, and the other to visualize volume antenna input.

Made using Processing.

Video of me playing (without video effect applied):    • Theremin Dance of the Sugar Plum Fairy  

Music:
Nutcracker - Dance of the Sugar Plum Fairy
