It might look like a chunky case, but the Pocket Projector for iPhone 4 from Texas Instruments and Brookstone offers your customers on-the-go video projection instead of device protection.
Inside is a TI DLP Pico projector chip, together with a 15 lumen LED lamp, a 0.5W speaker and a USB-rechargeable 2100mAh battery (also usable as a back-up batery). The companies claim it projects images of up to 50" in size from 2.4m distance with 640 x 360 resolution.
Image control comes through a focus adjustment knob.
It is compatible with apps supporting dock-connector video out, including the stock video, photo and Youtube apps.
