HaHaHa!!! Very good you remember it (David Bowie). You say you were born in 1978. I was 31 and, and still having fun. It is so very fascinating what these things can do. Like a giant erector set and you can build whatever you want. Truly amazing stuff. I have searched think I have an answer for the planks. You have mention sub division surfaces. I did have a clue. But have done some checking and you have given me many hour of fun? Yes it is fun. I will study on them and see how it comes out. It has been interesting Falott, not to mention informative. Thanks again!!!!! Sex, Drugs, and Rock 'n' Roll
