loop
it moves the cube around in an arc controled by the arrow keys, all you have to do inside the main loop is to place the cube in the center of the arc, turn it left or right by a small angle, then move it backwards the distance of the radius, then just keep doing this over and over, placing it in the middle, turning it a small amount and then moving back to the radius again, simple.
