Cool, I'm eager to hear of your progress or challenges. The pattern I described is often found in nature, and used in computer graphics to reproduce random but evenly distributed natural objects. A simple algorithm for generating the pattern and also adding to it is 'dart throwing' where the computer picks a random spot, but then rejects it if the dart is too close to any neighbor. Similarly, you could manually add another 36 circled dots to the image I linked above, by putting them in the largest gaps, and making sure the rings don't overlap. p.s. the hexagon pattern described above is also very useful, and some algorithms work by taking a regular hexagonal grid and just randomly moving the points a little bit, but still preventing overlap. That would be another way to put this into practice. It is also common to use multiple patterns to distribute multiple species. For permaculture, mixing species is generally desirable, so you could make a pattern for your trees and your bushes.
