Turn your iPhone into a fully-functional projector, with the MiLi Pro. Aesthetically, it looks like a slightly bulky case. When flipped open, you got yourself an "LED-driven projector" that outputs 640 x 480 images. This accessory is expected to hit stores in September. Click here for first picture in gallery.
It's got a 640x480 resolution, so it probably won't look all that good at 70 inches, which is why they recommend 40 tops. Also, at 10 lumens, you'll be lucky to get 30 inches in a dark room.[via Gizmodo - Phonesuit]
