A harmongraph generator made with quartz composer. Using transparent png as a texture, the composition modulates the x, y position using sin / cos waves while the image scales. Expensive and a little slow, but the process of watching the images being made is nice. Some of the final images produced by changing x, y position, parameters to the waves, switching presets, alpha and colors (using a MIDI controller) were usable as stills and textural elements.

The zip contains a version controllable by the keyboard and another with controls in the parameters. It is designed to be controlled with a midi desk. You will need to dig into the patch to explore the principles of the harmonograph generators. You may wish to add a clear patch. To see things better. I used the included QCToMovie application to render movies with alpha of the animated textures to be taken into After Effects.
