Finally posting some screen shots of the modeling of the tubes. Turned out to be a lot more difficult than i thought since i have a Mac and trying to printscreen without a PC 'printscreen' button on my windows side...not an easy task.
The individual tube towers are located on a hexagonal shaped plan and remain within the shape at all times. Their centers coincide with the edge lines of the hexagon and can move back and forth, but never move off the lines. This creates the 'swaying' motion as i have been calling it and keeps the towers stationary to some extent.
CONSTRAINTS:
The circular plans never change in size of diameter and their centers coincide with the hexagon edges. Coincident with the corners of the hexagon are construction circles with undefined diameters. This allows these circles to change shape but never leave the hexagon corners. Finally, the construction circles and the main plan-circle are made tangent with one another at all times. This creates a boundary that keeps the central circle from leaving the edges of the hexagon. At all times, the central circle and two edge circles must remain tangent to one another.
Once this process is repeated along all 6 sides of the hexagon and all the circles are tangent with one another, moving one circle then in turn shifts all the circles in the entire plan. The plan now mimics the FOA bundle towers.
