Inspired by @Paddle2See's ZenDoodle ( http://scratch.mit.edu/projects/17067495/ ), but I do not use code from the project. If go inside, you notice that there are 4 lists. You were expecting 8 variables, not 4 lists. Anyway, each lists contains a point's "info", or x/y position. The first item is the x, and the second item is the y. I use lists because it saves the amount of variables you must use, and a lot of variables is very annoying.
