These self-assemble lampshades, or Infinity Lights, are made up of quadrilateral, interlocking pieces that can be assembled in a variety of ways. The infinity lights come in kits with 21-30 pieces, assembly instructions, and a hanging cord. They come in a variety of colors that display some great lighting effects! They are so versatile that they can be used as a conventional ceiling lampshade, accent light, table mounted light, or used as a floor lamp.
You can buy the infinity lamp pre-assembled or disassembled. Of course, the pre-assembled lamps cost a bit more. I imagine a colored lightbulb would look pretty neat inside of these!
