Both versions of Waviary are free, now through Sunday. This is a simple little app for ambient jamming.

iTunes Description:

Waviary is a new, interactive musical artwork that is part instrument, part generative ambient music machine, and part virtual wind chimes.

Simple multi-touch control allows anyone to effortlessly create lush ambient soundscapes and environments, or simply listen as Waviary generates it's own "forest-like" sonic environments. The generative player can run while you play as well, allowing for a randomized ambient jam session.

A sleep timer is included...put on headphones and let Waviary's weird, wonderful sounds lull you to sleep.
