Importing Shadertoy code into Codebox: Help needed.

I've found a couple of Shadertoy examples that I cannot possibly live without importing into Max.
See: https://www.shadertoy.com/view/4s23zz, and https://www.shadertoy.com/view/lsl3RH
The author of these shaders has very helpfully provided a step by step guide into creating these, http://www.iquilezles.org/www/articles/warp/warp.htm, so it seemed like the perfect project for a simple code-flunkey such as myself to learn something along the way about GLSL and Gen. Alas, I have fallen at the first hurdle and can't get anything happening. I've included a patch that has been butchered off the Shadertoy Tutorial patch, and included a jit.gl.pix that tries to get the code to generate an image, as well as a jit.gl.pix that tries to get the code to process an existing noise/fractal image. Does anyone have any ideas on how I could possibly get the first few static examples shown in the step by step guide mentioned above?
