Thanks everyone for all the great comments! I hadn't realized that this particular arrangement of blocks has been published. It was just one of those late night "oops" moments for me. I too, like it better than the more traditional presentation, but was working on drawing up the original as my son had seen it years ago and then the variation with the different colors. He had told me that he wanted something to remind him of our scuba diving trip to Cayman Island when he was a teenager. The yellow I added was to be the sunshine on the water and hopefully a sign of better things to come after the storm, as he is recovering from a nasty divorce.
How funny, I just got an email from him saying he thinks he likes the "mistake" the best! He will make the final decision tomorrow and then I can get to work. I appreciate all the input. Ann in TN
