Look at these fun lamps I found! These are the Bottle pendants made by swedish designer Mattias Ståhlbom from TAF Arkitektkontor. What is fun about these pendants is that they can either be hung in the ceiling or kept on the the ground or used as table lamps.
You can keep the cap in a neutral color or have it painted in a fun and bright color. "Use it as a pendant, on the floor, on the table or on the wall. Use it everywhere, even outside." is what Ståhlbom says about his design. You can visit www.tafarkitektkontor.se to see more of Mattias.
