Alternative shader for the AudioVisualizer sample. See: https://github.com/paulhoux/Cinder-Samples

Test application for the Cinder framework, showing that recalculated normals (based on the average of all connected triangle faces) is just as precise as the original normals (calculated from sphere mathematics).

Adaptation of ShaderToy's AudioSurf shader for Cinder. Actual audio data is replaced with random noise to keep it simple. I kept the original shader code without making any changes. Note that ```iResolution``` must be passed as a Vec3f.
