A new iPhone case has been developed with a projector housed inside of it.

The Monolith case, developed by Japanese accessory maker Century, manages to hide a projector and battery pack inside itself, while still offering a decent level of protection for the smartphone.

While tiny projectors like this are still largely unable to compete with the image quality of full-size devices, the Monolith case delivers images of up to 60 inches with 640x360 resolution. The pictures have a 1000:1 contrast ratio and 12 Lumens of brightness, which means that they are best watched in a dark environment.

The battery pack looks likely to be one of the most useful aspects of the device, allowing people to use the projector without draining their phone's battery life. According to gizmocave, the projector battery requires four hours to fully charge, but it significantly reduces the impact on the iPhone's internal battery.

At the moment, it is only possible to buy the device on the Japanese market, and it is rather on the pricey side. But this could change if it takes off, which given the incredible popularity of the iPhone itself, could well be the case.
