David, It took me awhile to visit your blog and grasp what you are doing. If I understand it right this is very exciting. As Rob is injecting his constant pursuit of design elegance in reworking KSS, the resulting "formula" could generate designs approaching the awe of Steinar's but be, in addition, easy and economical to build. To get an idea of what is involved, how many parameters are used to generate a part like a bow? Or is this not a right question to ask?
