Michael Jackson patented a gadget to perform dance magic

DVICE: "As we mourn the loss of spectacular dancer, frenetic and staccato singer, and professional weirdo Michael Jackson, the gadget world reminisces about a patent Jackson filed in 1993. Remember that supernatural, gravity-defying 45-degree lean Jackson performed with his troupe of dancers on 'Smooth Criminal'? Jackson used wires and harnesses in the 1988 music video, but that wasn't possible when he performed the trick live in 1992."
