old + new skool
Old skool on Win 3.1 Take screenshot of user's desktop folder. Set it as wallpaper. Then minimize the actual desktop folder. User clicks and clicks... Could probably do that yet, on desktop centric folk.
New skool, for Apple Fanbois. Turn buddy loose on my iTunes (he _always_ wants to choose) which drives the stereo from the laptop. Meanwhile, use iTunes Remote on the iPhone to mess with his selection. Starts, stops, restarts, song changes.
(sure you could do this with the appropriate Android app + scriptable Amarok/Rhythmbox)
