Lightpack is an open-source device, which lightens your computer or TV screen to strengthen the presence effect. The device needs to be mounted on your TV or computer screen and to be connected to your PC, Mac or HTPC via USB. The software analyses what you currently have on the screen, be it a movie, a game, or anything else, and sends this information to the Lightpack device which in turn lightens the surface behind the screen with matching colours using the RGB-LEDs available within the Lightpack device.
