Plasma balls create a good electromagnetic show especially if they are controlled by a music player.
This device named iSound does the same. It has a Plasma ball that responds to the beat of the music being played on its four speakers. iPod lovers don’t find any thing special for them in the device except a simple iPod stand.
The system works well with any music system as it has a simple headphone jack. Other than the main function there is nothing more in the device.
The iSound website has priced it at $150 but you can easily get it for $90 from Amazon.
