Time Dilation Demonstration

One of the simplest demonstrations of (informatical, not relativistic) time dilation in consciousness, is to watch fans (or wheels) spin. Every observer sees a different strobe pattern.  In fact, each person sees different strobe patterns, as the rate at which their subconscious optical processes occur ... is in flux. We thus simply observe the framerate of our minds changing. The wheels out there are not changing - they spin constantly.
