“Spin” is a persistence-of-vision keychain prototype that, when spun through the air like, say, a lasso, displays a clock face in the air. There are even three different display modes, including an ‘analog’ mode that displays a highlighted arc of the circle, with the leading edge indicating the current hour and the trailing edge indicating minutes.
There is talk of this design being picked up and mass produced by a couple of different companies; make that happen, boys, because I want it.
