In 1971 the latest craze was an electronic, music triggered, light box that flashed colored lights to the beat of your music. I built a 3 channel, 2 foot by 4 foot box that flashed blue lights for low frequency audio, red lights for medium frequency audio and yellow lights for high frequency audio. Here in the USA they sold these boxes at major electronics stores. Some of the Media Players today have a "Graphic Visualization" option thay syncronizes your music with a graphic display. I feel that this enhances your music listening experience. Maybe some day developers with bring back that option for our Maemo media players.
