Setup

Create a Shadertoy account. Either fork this shadertoy, or create a new shadertoy and copy the code from the Debugging Puzzle.

Let's practice debugging! We have a broken shader. It should produce output that looks like this: Unbelievably beautiful shader

It don't do that. Correct THREE of the FIVE bugs that are messing up the output. You are STRONGLY ENCOURAGED to work with a partner and pair program to force you to talk about your debugging thought process out loud.

Extra credit if you can find all FIVE bugs.
