light bulb ~ Lieberman's Levitating Lumen Art

MIT's Jeff Lieberman & colleagues back in 2007 made this lovely levitating light bulb...
"The bulb and the casing contain hidden circuitry [...] that uses electromagnetic feedback to levitate the bulb roughly 2.5" from the nearest object, and uses coupled resonant wireless power transfer to beam power from the housing into the bulb itself."
