Looping Noise Part 2: Infinite Tunnel Zoom (TouchDesigner Tutorial)

This beginner level TouchDesigner tutorial uses 1D looping noise for the purpose of creating infinite tunnel zooms that start and stop in the same spot (okay, technically not infinite, but it does feel like it goes on forever!) We will also look at a technique for getting smooth camera motion and more generally explore methods for manipulating instanced geometry.
