Nothing ruins an impromptu movie night like a sub-40″ television and a lack of fresh films. The former’s a non-issue with 3M’s Streaming Projector: the tiny device bombards your wall with up to 120″ of screen at a resolution of 800x480px, fueled by built-in batteries for roughly two and a half hours. As for the latter, the projector includes a Roku Streaming Stick, letting you watch anything from Netflix, Hulu Plus, HBO Go, and more, straight from Wifi; alternately, yank out the Roku and plug in any HDMI-compatible device.
