/diy/ - Do It Yourself

Can anyone think of a good way I could mount my cell phone to the ceiling of my car? Its so when I recline my seat I can laydown and watch videos while looking up at the ceiling.

The only problem is figuring out the least intrusive way to mount something to my ceiling that also makes it easy to take the phone in and out. The ceiling is made of cloth with some kind of foam behind it if that helps.
