Meet the CAST: a home entertainment device that connects all your devices and provides livestreaming to entertain you. It lets you stream and mirror any content from your device to the devices of your friends, so you can watch things together. The system consists of a CAST box, a camera, and a HDMI stick. With additional sticks, you can show your content on multiple displays.
CAST can be used for games, movies, sports, and everything else. More information is available on Kickstarter.
