Press SPACE, then wave your cursor around to draw things. Press SPACE when you've finished. Hold UP for bits of your cursor-waving where you don't want it to know you waved. Then, it'll redraw what you waved, hence the title of the project.
HOW THIS WORKS: This uses two lists, called 'x' and 'y'. It registers the x and y of your cursor and puts it in the correct list. Then, a sprite goes to that exact location.
