Waveform Necklace #1

This was my first attempt at the waveform project and I must say that pgreenland's code seemed to work great!! It was very simple to use and produced what I think as a great result.
I need to put it on a better chain yet but I told my wife I would allow her to pick that when I gave it to her. This particular one is my oldest son (3 right now) saying "I Love You Mamma."

I printed the trays using alternating colors and then just let the randomization happen from the "packing" of the discs in each of the trays. I was happy with the result.
This definitely won't be the only one I will do and I can't wait till my wife gets to wear it and people ask about it and she tells the story. She cried!!
