Previously unknown drawings by Leonardo da Vinci have been discovered, revealing the famed artist/inventor/scientist was even more ahead of his time than anyone realized.

“We knew that da Vinci conceived ideas vastly ahead of his own time, including helicopters, tanks, calculators, solar power, and even the theory of plate tectonics,” said da Vinci biographer Irwin Nicholl. “But who knew that list also included cellular phones, hair-metal rock ballads and the Rotisserie Barbeque Platinum 5000 series?”
