VOSC is best understood as a visual analogue of a traditional sound synthesizer. The medium of synthesis, rather than sound waves, is a vast quantity of on screen particles. By manipulating the size, shape, and frequency of the oscillators, an endless variety of moving patterns and textures can be created.
A primary mechanism at work in VOSC is the phenomenon of visual harmony as explored by the computer graphics pioneer and visual artist John Whitney in the mid 20th century. The oscillators of VOSC operate in accordance with Whitney's principle of differential motion, giving rise to harmonic resonances as their frequencies move across whole ratios.
This app looked good and in haste I bought it.
However the interface is archaic, it took me several minutes to figure out how to get an image.
Also, you can’t save to the Camera Roll. It forces you to upload to their website and then you have to visit the site and download the image. So no good if you are not on the Internet at the moment of your creativity.
