A tall tower, similar to the upper two-thirds of the Eiffel Tower
is shown in Figure 9. This tower was optimized from an initial
rectilinear set of joints and beams, automatically generated from
eight user-specified points (the four anchor sites and a four loads
at the top). We concentrated on the top two-thirds of the Tower
because the design of the bottom third is dominated by aesthetic
demands. Similarly, the observation decks, also ornamental, were
not sythesized
