Fake Front Camera
For those of you who don’t have a front facing camera, you can just attach OneMoreFace on the top of your device. It will reflect your camera back making it show the other direction. Although i’m pretty sure it does not work on all devices as each phone has it’s camera positioned differently. Its also just a concept but a really creative one. I would definitely buy this if it went further to production.[Source]
Something like that already came out a while ago—for people who have a jailbroken iPhone 3GS—in order to use FaceTime.
That was no biggie, as jailbroken 3GS was only limited to Facetime. You can use it for 10′s of video apps when it comes to Android.
