Light reading

Update 4/15: Welcome NYT visitors! The Fib you seek is here.

For those of you not caught up in Passover or Good Friday activities, a little sweetness and light at the end of the workweek:

Roxanne goes CF at home in the name of national security; this is a subject dear to my heart. Via her comments thread, I found Daily Pie, a blog by a likeminded writer and fellow Texan who provides charts on her energy-conservation efforts.

BBC Science reports on a new kind of lighting technology, the organic light-emitting diode:

The organic light-emitting diode (OLED) emits a brilliant white light when attached to an electricity supply.

The material, described in the journal Nature, can be printed in wafer thin sheets that could transform walls, ceilings or even furniture into lights.

What would you turn into a light fixture if you could? I think magazine and book pages that light up would be pretty handy. Knitting needles and yarn, too. If there were a way to combine OLED with polygraph technology so that politicians, spokespeople and lobbyists light up when lying, that would be useful, although it might create some light-pollution problems.
