One of my friends has had a Philips speaker set for ages with ambient lighting, fans and a rumble strip that works with many games. It's pretty cool but definitely not essential I really don't see why anyone would go out of their way to create ambient lighting via a Raspberry Pi though.
That being said if it was the right price I would get it for games like mario kart, the video is really nice.
