When I was 8 or so my family got one of those tactile floor lamps for the living room. Touch it once to light it, twice to make it brighter, thrice to illuminate all, and four times to return the world to darkness. It was the coolest thing I'd ever seen in real life. I'd sit there turning it on and off, on and off, until my mama yelled that I was going to break it and then she was going to clobber me. I wonder if this Levitron floating lamp stirs feelings of similar awe and fascination in kids today.
The Levitron's shade sits atop a magnet that hovers 3 cm above the lamp's base, producing a neat hovering effect, as well as encouraging passersby to give it a spin. When rotating, the shade's design puts on an spiraling geometric display not quite as entrancing as the Fletcher Capstan table's transformation, but possibly on par with the Revitalizer wax lamp's slow oozing and self-regeneration.
Levitron table lamps measure 20-1/2" tall and output light from 6 LEDs.
