The nature of the process in Gridcosm has a built in tendency to high density that is not present in other grids done in the past on SITO. By shrinking down a finished 3x3 grid into a much denser middle starter square has always led to dense squares around it, especially those that attempt to carefully blend. It's the nature of the beast and also it's uniqueness.
I would very much like to see another grid making engine in which the seed middle image is sent by whoever. From there it would proceed like the current Gridcosm. When completed it would be archived with a level number. Only then would the next level be open to whoever was first with a new see image. "Eternal Griddle"
