That is an insanely awesome idea. Now watch as I steal this idea from you, since you have not as yet patented it and likely would not anyway since the concept is beyond you being of Austrailian descent and thus lack knowledge of the U.S. patent system that I, in fact, DO know of, and make billions of unholy amounts of American dollars that I will use to purchase those things with which I am well pleased.
