I just came across this article on Slashdot about a company that's using fiber optics to bring sunlight indoors to lower electricity bills and heat from incandescent lighting.  Sounds promosing so far to me, but it'll be 2007 or so before any of it hits the market.

I wonder if I'd be able to talk someone into getting something like this for my desk at work.  I work in a cave, which doesn't really bother me, but the only light source I have anywhere near my desk is a makeshift light fixture.  It used to be a shop light.  It really wouldn't be so dark, except my desk has been cubicled in by a bunch of tall file cabinets.  Not much light comes in over them.
