“L’Angoisse de la page blanche” (The Anguish of the White Page) by Ariel Schlesinger is a kinetic installation where 2 A4 sheets are pressed against each other and spin at the same time. Yeah you should watch the video.
Here's a funny one, whether or not it is legit, I don't know. But seeing a plasma screen rotating will keeping the picture in place, is definately cool!
