The MirrorCase lets you lie your iPhone almost flat and point the camera at your object of interest, and record videos or take photographs.
This is possible thanks to a clever mirror and even more clever free app that records the images negating the reverse effect of the mirror. You can tell the app to save the video in portrait or landscape. There is also the option to display any photo from your library while the video is recording, to hide your intentions.
In a way, the timing is perfect. The hidden camera footage from Mitt Romney's $50,000/plate fundraiser demonstrates the potential use, or abuse, depending on your perspective! I would not want to see these used in a locker room for example.
Since that first preview, Apple has released the iPhone 5, which you might think makes the case obsolete. However, I tried the MirrorCase with my iPhone 5 and it works! You just can't slide the end cap on all the way, but you can use the mirrored camera portion just fine. Or you can repurpose an old iPhone 4 or 4S strictly for use as a hidden nannycam.
An iPad version is in the works. Either solution could also be a nice way to capture college lectures without having to hold your iPhone or iPad the whole time. The MirrorCase is a neat idea, well executed, that, in the right hands, can be quite useful.
