In the dark

The plenary sessions of the meeting are signaled not only audibly with chimes but by dimming the lights, particularly in other areas of the ballroom. But in this conference they're going nearly to black and for extended periods of time. A bit difficult for those of us who, for various reasons, wind up in the adjacent vendor area near the only available wall outlets. (For my part it's been to complete the graphics for a description of the Smart Grid for a colleague's green building textbook.)

The other fellow at my table had the solution: his laptop has a built-in LED to illuminate the keyboard. What a great idea.
