I just got back with a trip out west. One interesting thing I've noticed while riding through rows of orchards in California is the voids you see between perfectly placed trees when you're going fast enough appears to be a fractal. I simulated this situation using the mean of many images of randomly offset rows and got the following image

Pretty cool. I'm not sure if there is another way to predict the location of the voids (or even how that would work in the first place). Maybe I'll look at the math at some point
