@handmade_ghost I had a couple of favorite doodling patterns that would repeat and grow to cover most of the page. For example, I'd draw a maze of rectangular boxes with gaps in their walls here and there, and then draw a line bouncing off the walls like the old Pong type games, going inside and between the boxes till the spaces were so full of crisscrossing lines there was no room for more. I did this through school, and in many work meetings for years.
