Arduino enthusiast Chris Mitchell has created a fantastic persistence-of-vision device that doesn't require a lot of hand-waving - instead eight RGB LEDs are fitted to a ring that rotates at ten revolutions per second, giving the illusion of an 8 x 50 pixel LED display. Controlled by a Freetronics LeoStick the POV globe can display a variety of messages or graphical effects, as shown in the following video:
That's a fantastic item which looks great and you can make yourself, so review Chris' website for more information.

So what is a LeoStick? It's the Arduino Leonardo-compatible board that's cheaper and smaller than the original:
Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.
