The Nebula Capsule from Anker is about the size of a soda can and contains a Bluetooth speaker as well as a full-on projector. It has a resolution of 854 x 480 and can throw a picture on your wall that's up to 100-inches. It's battery-powered, so brightness is limited, but I saw one in person this week and was impressed by its performance. The Nebula is currently on Indiegogo, where it raised nearly 10-times its $50,000 goal with a month left to go. It costs $269 if you jump in now, or $349 if you wait.
