This is a video comment on a point mentioned by professor Leonard Susskind in his sixth Stanford lecture on Quantum Mechanics (www.youtube.com/watch?v=tKbzlOU_ETk at minute 12:00) that it is quite hard to think of a classical setup which gives the same probability distribution as polarized photons. This video gives a proposal for such a setup, where ordinary needles steered by a pilot-wave are shot towards a wire-grid. Technical knowledge of quantum amplitudes is necessary to follow this video.
