Who knew that a big bunch of white plastic balls could come together and make such a beautiful lighting fixture? It seems all the best creations are surprisingly simple, though, so this should be no exception. Designed back in 1969 by Verner Panton the Ball Lamp Pendant
it's also known as the Wonder Lamp. The white balls are suspended on nylon strings, which makes them look like they're floating around the bulb inside and provides a warm diffused light. The Design Within Reach description mentions that the balls "bounce against one another with a satisfying tap," which is cool but I can't think why you'd be knocking your lamp around to end up hearing that sound, unless I'm missing something. Currently on sale for $998.
