constructor

ctor_demo.mp4

A platform for live shader performance. Key features:

UI and rendering are 100% web-based
Supports s4r (a stack-based metalanguage for writing shaders) and GLSL
Audio FFT available to shaders
Changes to shaders are loaded on the fly
Changes aren't visible to the audience until you click the "take" button (and errors won't be sent to the audience at all)
MIDI controller input
Any number of outputs through any number of computers (which don't have to be your workstation!)

Documentation is lacking because I'm mainly making this for myself.
