Waterproof Remote Control?

hi i was just wondering if anyone knows of a remote control for the iphone that is waterproof? id really like one because when im in the shower i love to listen to music, but sometimes i wanna change tracks and i dont wanna touch the iphone in case i damage it with water. I think it'd be a great idea because im sure there are many people who'd like to do the same. they should make one with suction cups on the back so then u could just mount it to your shower tiles.
