Overview
Tunnel is a 3D audio visualizer: talk, sing or play music. Tunnel will take audio input and turn that sound into a 3D tunnel that you fly through as it twists, turns and warps.

Tutorial
If you have a built-in microphone you are ready to go. Simply make a noise or play some music. On some models you will need to attach an external microphone or audio source. That's all there is to it.
