From the developer:
SpaceTheremin is a virtual mouse-controlled theremin. Unlike a standard analog theremin, which typically has a sinewave oscillator and some basic vibrato, SpaceTheremin lets you choose from six different oscillator types (sine, square, triangle, sinc, saw, and pulse). The same waveforms can also be used for vibrato.
