iPhone 4/4s head holder

For those who don't have enough money to buy Google Glass, here is a device that gives you ONE of the functions it has.
Have you ever had an experience where you want to record your hand work with your iPhone camera but you only have two hands, one for work and another for work...you look around for someone to hold your iPhone but you don't see anyone or maybe you don't even have a friend to ask? Here's a solution for you. All you need to do is to set your iPhone and press + or - button, and this device holds it instead of you while recording.
Please not that YOU NEED TO MAKE YOUR HEAD BAND BY YOURSELF. I used gum tape for mine, but if you want it to look more neat, you may want to use some band or something but don't worry–you already look awkward with this device.
And sorry for iPhone5 and 5s users, but for you guys to use, you need to edit the Rhino file. I'll be glad if this is your first time regretting having the latest version of iPhone :)
