Might be a noob problem. Low poly refraction?

Hi! I have been trying to attempt to recreate this technique that is used in cinema 4d in blender. Here is the technique I am referring to http://greyscalegorilla.com/blog/tutorials/render-an-abstract-refraction-low-poly-look-in-cinema-4d/
I am currently using the newer cycles rendering system in blender and I am currently unable to create that effect. I used blender years ago and I just got back into using it to find out that a lot has changed. I would really appreciate if someone would take the time to help me out!!! Thanks!
