La Tabla is an open-source interactive system projected on a table

La Tabla introduces a groundbreaking way to interact with computers. Rather than using a finger to click on a mouse or poke at a screen, you reach into the simulation world with two hands, bringing the full force of your hominid dexterity and playfulness to the table. Because you can put whatever you like—coins, stones, books, drawings, yourself—into the simulation world, play is surprisingly improvisational and open-ended. Playing with others doesn't require sharing a mouse, keyboard, or network connection. Everyone sees and touches the same thing, which is such a profound way to interact that we take it for granted during our everyday, non-computerized, life.
