I found this kind of amusing.

ModTones sells lighter wallpaper ("RockLighter") for non-smoking music fans that find themselves ill-prepared for concert hits. "..Find yourself awkwardly swaying your empty hands over your head during rock show power ballads? Or worse - holding your cell phone aloft, but mistakenly hitting a few keys during a particularly intense solo, and dialing Dubai by mistake?" Thank you, ModTones.

This, of course, leads to a whole genre of concert wallpaper possibilities (ganja, panty, or 'birdie' wallpaper..?)...which I won't get into.
