just move your mouse around and watch the circles calculating the mouse position
"mouse x" or "mouse y" blocks aren't used is this project, the only thing that this project uses is math. the secret is that, if you have three points in three different locations and calculate the distance from these points to the mouse, it is alrady possible to be sure what the mouse location is basend only in the position and distances of these points. the distances can also be interpreted as circles, and these are the circles you see in the project thanks to http://paulbourke.net/geometry/circlesphere/, for providing circle-circle intersection
