A levitating wirelessly powered lightbulb.
The floating light bulb, uses a special bulb, inside which magnets and circuitry are hidden. Using a magnetic hall effect sensor, an electromagnet, and a [modified] PD feedback system, it floats a lightbulb stably in the air, while power is transmitted wirelessly from the base of the sculpture into the bulb. LEDs in the bulb rectify this AC power and convert it to light.
