These are quite amazing. Found them on thingiverse this morning. (http://www.thingiverse.com/thing:351449)

They are such a brilliant idea, and pretty easy to assemble it appears. I've always wanted an edison lamp in my room :)
They are made in ABS and the edges are glued together. I'm guessing those are LED lights?
