Made a geomorph on graph paper last night, that was an idea conceived in the morning. Now I need to figure out how to excise the blue grid using GIMP. Also a bit blue in background and there is some cocked grid from the page behind. Will fiddle some more with the files.
Hit it with a Threshold per +Eric H and a couple 1 px Gaussian blurs to reduce the intense pixelation a bit. Liking it better.
