“My son created this just before we went on vacation (road trip). He wanted to watch movies on his iPod but didn’t want to hold it. Its a angle L with a piece of plastic that has 3 suction cups that he stuck to the window. My son took an old case and zip strapped the angle L to it. His ipod would slide in and out. Not a bad invention, my son is 15 yrs old.”
Reason number 23 on why you should never toss out old tubes, they make great iPod / iPhone holders.
