I could use an algorithm for repeatedly drawing an object in an ever-increasing spiral -- as if the object were spiraling away from its center-point until it is completely off-screen. The object does not appear to get closer (larger), by the way. It will be staying the same size throughout the exercise.
I know how to draw the object. I just need a way to calculate each new origin for the object, either as a center point or corner point.
Does anyone have such a routine laying around that they would be willing to share?
