@bigchungusmc As you choose larger and larger grid sizes, the objects decrease in size until you can hardly see them anymore. Try running 150-150-5 and you'll see that everything is basically a speck. 200-200-5 would be even smaller. That being said, I'm adding a failsafe to prevent the grid from being any larger than a certain point to make sure this doesn't happen again. Thanks for spotting this, and thanks for the complement!
(Edit: now you can't go past 180 rows and 250 columns. This makes everything about a pixel large, but still visible)
