Atlas Obscura points our attention to a site in Oregon known as the "duplicative forest."

The poplar trees growing at this 17,000-acre farm are "all the same height and thickness," we read, "and evenly spaced in all directions. The effect is compounded when blasting by at 75 mph. If you look for too long the strobe effect may induce seizures."

While this latter comment is clearly a joke, it would actually be quite interesting to see if optical regulations are ever needed for the spacing of roadside objects. If, for instance, the Duplicative Forest really did induce seizures in motorists—but only those driving more than 90 mph, say—thus exhibiting neurological effects, what sorts of spatial rules might need to be implemented? Every sixth tree could be planted off-grid, for instance, in a slight stagger away from the otherwise mesmerizing patterns, or the speed limit could be rigorously enforced using bumps—in which case you would know that, just over the horizon of your car's speedometer, a strange world of neurobiological self-interference looms, as the world around you threatens cognitive failure in those passing through it at a high enough speed or intensity.

On an only vaguely related note, meanwhile, fans of Fredric Jameson might recall his spatial analysis of Alfred Hitchcock's absolutely excellent film North by Northwest—specifically Hitchcock's use of rhythmically placed, identical trees.
