Oregon Scientific's Portable WiFi Projector comes with a hinge, flirts with your ceilingSee all photos
Speaking of which, the concave top of the base is actually a funky touch-based controller for the brightness and volume: slide your fingertip towards the center to take things down a notch, and slide outwards to crank them up. As for audio, you'll have to place the base on a hard surface to let its vibration speaker do the job. The audio effect will obviously depend on the surface material, but apparently the projector's pouch will also serve as a backup sounding surface if all else fails.
While our demo used a wired connection, the final product -- as suggested by its name -- will utilize a direct WiFi connection with smartphones, though you'll need to install Oregon Scientific's app to make the magic happen. Android shouldn't be a problem, though we do wonder if Apple will actually approve said app since there's no love for AirPlay here.
There's still a long way to go for this neat little beamer -- we were told to expect it in the second half of 2012, which should give plenty of time to save up for the estimated $640 price tag. Yes, very ouch.
