Doug, It is a very impressive piece of work. My wife would love it if she could figure out where to put it! I think it's value is as one piece. While the value of the components adds up, the real value is in the time and ingenuity in designing and building it.
I see where you say each table is in 4 modules. Does that mean each helix is a separate table? Does each helix easily come apart or can be removed from the tables? I think as Landsteiner said, portability and ease of putting it back together again will play a huge part in how easily it is sold.
