I'm currently collecting accordion mirrors for my bathroom, and while digging around for some on the internet, I found a great deal on this accordion lamp!
Only $22.50 from Micro Mark.
It's not as designed as some of the other more expensive versions, but it would still be awesome as a bedside lamp, desk lamp, or on either side of a couch? Ooo, the possibilities. You could also spray paint it and get an edison bulb.......
Here are some others:
White Version from Affordable Products (though I don't see how to order)
PBteen Lumi (disccontinued - boo.)
Accordion Library Sconce from ZFurniture.com
