Tired of watching videos on your small iPhone 4/4S screen? Here’s the most whimsical approach to increasing the image size and sound volume from any device. The Mini Cinema for iPhone 4/4S from OhNeed is a very low-tech approach to turning your display into a bigger screen. The Mini Cinema has an old-fashioned horn to passively increase sound volume. What appears to be a Fresnel lens is placed in front of your phone’s screen to enlarge the image. It can be used vertically, or horizontally with the extra support piece for the phone. It looks a bit bulky to fit in your bag, but it does come with a storage pouch – and you certainly don’t need to worry about finding a power source to use it. This low-tech solution is available in black or white for $68.
