Yup, it sounds like a disco ball, thanks for the reference. Seriously, I wonder what would be more effective, ie "brighter", a ball with 1000 small mirrors or the same ball with 10 surfaces and a high, irregular spin rate? Of course the 10 surface ball would flash but it might be a lot easier to spot. I am betting the design they have will require binoculars and good eyes like the sputnik does.
