I saw one setup on Amazon where the tennis ball on a string was run through a pulley wheel and the end of the string was attached to the end of the garage door. So when the garage door closes, the tennis ball raises up out of sight. When the door opens, the tennis ball is lowered to windshield level. Pretty slick, but more effort than I want to put into it.
