The picket fence There was a fence with spaces you could look through if you wanted to. An architect who saw this thing stood there one summer evening. Took out the spaces with great care and built a castle in the air. The fence was utterly dumbfounded, each post stood there with nothing round it.

Right-Angle Doodling Machine A Game by Clive Thompson openprocessing.org You draw one single line. It can be as long as you like. To start the line, you put your pen down. You can make right-angle turns only, either 90 degrees or -90 degrees. You cannot back up. You must always move forward. You don’t lift your pen until you’re ready to stop. When you lift the pen, the doodle is done. drawingcodegames
