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.
