Le Biniou is a tool to create images from sound. It has a long history, has been inspired by many OpenSource projects, and comes
WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
Le Biniou is made of more than 80 plugins, that react to an input source (usually, a soundcard). After more than ten years of existence, and countless hours of run, it creates new, never seen before, mind-blowing effects.
You might want to give a look at the screenshots or videos to get an idea.
About the code: It was a deliberate choice to keep things as simple as possible. Thus, Le Biniou works on 8bits-indexed buffers, which allows to easily develop cellular-automatons, or similar algorithms. No OpenGL. No MMX/SSE2/assembly optimizations. No GPU programming. Only simple plugins. The magic of mixing plugins in a chaotic way, based on a sound input, does the rest.
WARNING: We are not responsible for the side-effects of using Le Biniou. But we hope you will have some fun playing with it :)
