This device is the Village Bike of Sci-Fi, everybody's had a go. It's been showing up for years in various SF TV shows and Films, what it does nobody really seems to know but hey it has flashing lights and looks cool so it must be important...mustn't it ?!
I'm sure what I have here is only a tiny amount of this devices appearances, I can almost bet it's been in Battlestar Galactica or Buck Rogers, I bet it was in Dr. David Bruce Banner lab in the Incredible Hulk TV show, and if it wasn't then why not. If only the Star Wars prequels had used this device, maybe that's what they were lacking. Every home should have one, this and a plasma ball.
Let me know of any other sightings of this device.
