a big red button Back in the day when we were building our fusion reactor at Fiat Lux, we saved some money by buying an old Varian ion implanter (for the HV power supplies). We scrapped whatever good parts we could find off it. One of the goodies we got out of that thing was an absolutely huge (~5 inch diameter) red button with the word STOP on it. I always wanted to find a good use for that button, because it was just so amazing! But the thing about a fusion reactor, is that turning it off is pretty easy. The only thing that it might have been useful for was as an emergency stop button for the high voltage power supplies. And the only time that would have been useful, we didn't think to hook up the button beforehand. I like your idea. The aesthetics of web-based design seem rather confined to the screen, and bringing that control of information out of the screen sounds like a cool idea.
