This is based in some of the visual feedback ideas I've been working with.
It's a desktop level app that produces "paint" squalls of different textures... this is an example of just one of the various settings. It responds to your body movement and paints over whatever your desktop wallpaper is, using this particular setting.
This is a screengrab from a version done a couple weeks ago. It used an alpha build of Kineme's Quartz Builder to "app-ify" it. I also have some settings that control the visual seed with multi-touch / TUIO, AR Toolkit, as well as some openCV options using the Kineme OpenCV library. It's turning into a "mega interactive" art application.
