re: Adjustable Cell phone stand

Yeah that's right. I have made invisible flush hinge many times. One day I was testing one between two boards for making a box. The boards were lying flat on my bench and my cell phone next to it. I went for lunch. When I came back and saw everything the idea struck me that I could turn it into a small stand for the cell. 
I made it for myself and when I showed it....I was making many. It's alot of work though for a stand.
