http://subpixels.com - OpenGL shader experiment with Praxis LIVE (http://www.praxislive.org)

Implementation of the "Road to Hell" shader (https://www.shadertoy.com/view/Mds3Rn) by rez (https://www.shadertoy.com/user/rez) as a video:opengl:filter component, with a few tweaks to allow the shader to be controlled by external parameters.

The parameters are MIDI mapped, with MIDI data coming from my Korg nanoKONTROL (using 5 of the sliders).

The output window is captured as an OpenGL source into XSplit Broadcaster, which is what I used to do the local recording.

Apologies that this is only 360p video - I wanted to keep the frame rate up to show the audio-reactivity clearly.

The parameters are MIDI mapped, with MIDI data coming from an external program that does FFT audio analysis and a hardware knob (on my Korg nanoKONTROL) for the forwards/backwards "speed".
