Marching squares is a type of algorithm used to generate graphics. It's basis is fairly simple and pleasing to look at, but the algorithm can accomodate more detailed graphics. I implemented the bare bones of the algorithm in the canvas below. For fear of butchering an explanation, I won't go into detail about the algorithm, but if you are interested in it just look it up on the all too pwerful internet you are currently on.

INSTRUCTIONS: Simply click and drag to see what happens. However, this does NOT work with ONLY clicking (you have to click and drag on the canvas). If you wanna restart, simply refresh the page.

May or may not work on mobile browsers.
