The ipico Hand-held projector, in conjunction with the ipico app, turns your iPhone into a portable projector, capable of displaying videos, documents and more on a nearby wall in sizes from 5 to 50 inches.
Says CBS News, "It's with websites that ipico starts to become really useful for business. Navigate to Google Docs, for example, and you can display any of your Google documents on the wall from your phone. Another useful function for the ipico: You can project the iPhone's camera, which means you can use it to project a close-up view of hardware or paper documents -- handy for a live demo before a large audience."
The $129 device works with iPhones older than the iPhone 5. Read more here.
