I ran across this light fixture and was mesmerized. The shadows cast by the light give the illusion that you are in a forest. It made me wonder what other options I could find that are inspired by nature.
This pendant from IKEA resembles a dandelion and, when lit, will also throw interesting shadows around the room.
The shape of this CLOUD light designed by Frank Gehry is flexible so that the owner can re-shape it by pressing and pulling on the fabric-like material.
There are certainly many other options but these three are my favorites.
