Here's one gorgeous and unique design: the Maria S.C. lamp by Pani Jurek. A pretty simple, well designed lamp and it just works. From afar, it looks like your regular chandelier, but really, they are rows of chemistry lab test tubes arranged and bound together with a circular ply board.
What really makes this great is the chance to customize it and make it your own. Like you can 'experiment' on it to make it more unique. Like adding different colored liquid just like you would do on a regular test tube!
Or like placing flowers on them like a vase! I kinda like the idea of growing plants on them. Cool!
