This is my first example I built from scratch. I was looking at the grid sample and decided to kick it up a notch. It's intersting how you develop the node network: you add and modify in a logical fashion but in the end you barely recognize (and comprehend) the finished work (it's like when building those complex Excel spreadsheets with a lot of calculations!)
Something is wonky when .dyn files are saved while Run Automatically is on, or perhaps this was a one-off case, but the above probably won't work as it'll be very slow to open and will result in additional incorrect connections/wires once open. I made some more tweaks and this version should work, file attached.
