Ripple Afghan

I've started making an afghan from the gorgeous pattern Neopolitan Ripple, from here:

I liked it because of the softness of the wave. I started a Crochetalong on Craftster, although so far I'm in the canoe and paddling alone, haha:

Mine will be cream, beige, and green. I also signed up on Ravelry for another year of 12" squares, so that will take some catching up.
