Shader Scrubbing experiment

Shader Scrubbing experiment from Terry Payman on Vimeo.

Made with the awesome Magic Music Visuals VJ software. http://magicmusicvisuals.com/.
Four Shadertoy shaders, each modified to accept an external variable instead of iGlobalTime.
It's then easy to "scrub" the shader, and to make it music-responsive.
