Just some intersecting lines forming random shapes.
A pattern of intersecting squares, triangles, and lines. I was mostly just playing around with the Shift-Click feature while my drawing tablet is out of action and thought this was fun enough perhaps to share. It could be used to make a wacky background, as a stained glass window design, or could even be a fun coloring activity. Will have to be sized for your needs.
Perhaps as a fun coloring challenge, use any color hues you like, but make it so that no color (blues, greens, etc) is side by side with itself.
Have fun.
