The white paper-like lampshades above are actually made of concrete. I found them over at Behance, and a couple of clicks on I discovered the dua shop where more beautiful things can be found.

The Like Paper series is designed by Miriam Aust & Sebastian Amelung and sold here. The corrugated cardboard light (pictured above) titled Beute and designed by Herr Wolke is available at the dua shop also.
