Spectra Brush for iPad

This looks like a very interesting cross over between sound and visuals. Here's the description:

Spectra Brush lets you paint expressively with sound. Use your fingers to paint while using your voice or any other sound to control the shape of the brush. Choose between eight different brushes to create different effects.

You can save your paintings to your iPad photo library.

Oh, and it is free!
