CIMG7573 Lampshades made of interlocking pieces
CIMG7573 Lampshades made of interlocking pieces, exhibited at the Maker Faire 2007. I think the exhibitors of these lampshades were giving away instructions on how to make your own lampshade in this manner.
Maker Faire was a two-day event that celebrated arts, crafts, engineering, science projects and the Do-It-Yourself (DIY) mindset. It took place in Austin, Texas in October 2007.
