@LeoLex_ @LingeringRegime You can make your PC play whatever sound you want when you start up/turn off (or roughly any task), so long as you have the audio files.
Mine's plays the opening guitar of "A Hard Day's Night" when it starts up ;)
@pgrammus 3D TV's can do anything a past -HDTV- can do, just that you can also watch stuff in 3D, but you can turn it on/off whenever, from what I was told.
