VOSC is a visual particle synthesizer that allows for the manipulation of large numbers of on screen particles through the use of oscillators. By manipulating the size, shape, and frequency of the oscillators, some very intricate patterns can be created.
A primary visual 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.
VOSC is driven by GPU shaders, which maximize the efficiency of the calculations necessary to position and render the particles. The performance of VOSC is therefore dependent on the capacity of your device's GPU. Those on typical mid-range devices (1GHz, single-core), can run VOSC at high frame rates with 64,000 particles. High end devices should be capable of 5-10 times this number.
