If you get a bright idea, a light bulb should appear over your head.Balloonatics Enterprises makes elaborate light bulbs, which when turned on, look positively uplifting.Apparently such "glowing flowers" bulbs were made by Aerolux Corp. and Birdseye Corp. as early as 1930 and were quite a craze in the mid-70s and 80s.
Here is a neat idea: air balloons with an electric filament inside. Should be safe enough
Not only this bulb is suspended in mid-air, it's also wirelessly powered... as you can see: 
All over the world millions of burnt light bulbs are thrown into garbage. How about recycling them into innovative, cool lighting designs?
