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.

A new way to create hand-drawn animation. So playful you’ll think it’s a toy, but it's secretly a robust app with a reimagined UI for animators and creators. Taking inspiration from music creation tools, using Looom feels more like playing an instrument than operating software - exploring lines, shapes and colors through loopable time and rhythm. Looom is all about looping animation with a smile. It was designed for professionals and beginners of any age and is already being used by some influential indie animators. A delightful environment to learn, experiment, practice and create drawn animation. Wonderfully musical, Next-gen dynamic non-destructive workflow. FLUID TIME No first frame or last. Looom’s threads are independent in length and speed, always tweak-able. INFINITE CANVAS Lets you go as deep or as far as you want thanks to a completely resolution-independent vector engine. OPEN-ENDED Looom uses SVG as it’s native file format. Your work can be viewed in browsers and opened in desktop animation software.
