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.

ABSTRACTOR: PAINT WITH GENERATIVE MAGIC Unleash your vision with Abstractor, a poetic drawing app for iPad and iPhone, crafted for artist explorers and playful creators. Paint with infinite possibilities, where every stroke pulses with generative magic. FLOW BRUSHES: THE HEART OF CREATION Dive into the soul of Abstractor with flow brushes, where particles swirl like living liquids, leaving hypnotic trails across your canvas. These dynamic tools respond to three unique velocity maps: • Stroke Paths: Your gestures carve flowing rivers, guiding particles along vibrant trails. • Image-Driven Flow: Import an image to shape a velocity field, infusing brushes with textured, directional energy. • Algorithmic Soul: Add generated noise or patterns to give particles a distinct character—turbulent storms or gentle ripples. Tune particle behaviors in real time, sculpting their essence like a visual composer. Blend these maps to create mesmerizing, emergent patterns that surprise and inspire, making every stroke a performance. Colors shift with stroke angle, pressure, or speed, weaving emotion into every line. Use familiar layers or bind tools to them for tailored magic. Paint over a color source layer, pulling hues from imported images to craft radiant distortions—flow brushes shine here, warping visuals into dreamlike abstractions.
