High quality LED animations for your next project.
 
This is a Shader and 5D Coordinate Mapper made for realtime
rendering of generative animations & artistic dynamic visuals.
 
This is also a modular animation synthesizer with waveform
generators, oscillators, filters, modulators, noise generators,
compressors... and much more.
