Click to draw (preferably while xRotate and yRotate are at 0). Space to reset. Note: drawing lower is "closer" while drawing higher is "further away" Up arrow to show settings and down arrow to hide. xRotate makes the drawing turn about the z axis, while yRotate makes it turn about the x axis. Warning: having both xRotate and yRotate on at the same time will deform the drawing (but still looks pretty cool)
