The lights I am showing you today have not so much in common but I like all of them!
The first case is a -literally- bright idea, lights made of vintage crystal decanters, after their bottom has been removed. They look beautiful in a cluster, the light sparkles as it passes through the crystal, adding luxury and elegance to the room.

Here's a lamp that looks like a book, designed by My-Seung Kim and Myung-Seo Kang, found on HomeDosh. The light can be adjusted by opening the book more or less.
The last one is a pair of lights made of wooden shoe trees, steel pipe and sphere lamps by Junction Products, a company that makes amazing things from stuff that people consider to be junk. I have a similar pair of shoe trees, I could try to make something like this.
I think all three ideas are very special and the addition of one of them in a room would immediately add character to it.
