In the year 3000, your lights will look like this

Or maybe in 10 years or so. Designer Ingo Maurer has come up with a nice-looking lamp utilizing custom OLED panels created by Opto Semiconductors. The panels are quite small: 132x33mm, or a bit more than one inch by five. A few of them in his tree-like configuration would make for a bright and even lighting situation. The designer is very excited about the possibilities of the whisper-thin, energy-efficient light sources. I will be too, if I live to see one.
