As a companion to the Line Drawing
sketch, this interactive program also uses p5.js. The best way to view it is to full screen your browser. In Chrome that means clicking on the green circle in the top left of the window. You may also want to go under view and make sure "Always Show Tool-bar in Fullscreen" is not checked.
As in the Line Drawing sketch, fun lies in discovering the interface, so I won't spoil how to play. It's not a game and there's no win state. Make sure you see that there is an interface at the bottom of the screen and you move and scale the gears.
This is still a work in progress, so it might evolve over time. Let me know if you have any feedback.
