John, how does this structure compare in height/scale to the Kitt Peak structure?
The area required to accomodate the shadow of a nodus that high for a good portion of the daylight hours must be quite vast - assuming that it would operate year round. The casual user would also have to be instructed to disregard the errant linear portion of the shadow as well, wouldn't he? Perhaps this is a good candidate for a very well done (sitework & landscaping) noon analemma? The nodus could be flat as Bill suggested, perhaps with an aperture or lense in the center of the disc to give a good spot and generate additional interest. If the bridge is oriented N / S then the analemma would proceed nicely along the main axis of the bridge, though I haven't checked how much longitude correction would be required for that site. Fun to think about, though. I will certainly watch with interest. Best, Jim Tallman Sr. Designer FX Studios 513.829.1888 -
