I most certainly did. Technically it was a temporal consciousness transfer engine to traverse the time-space continuum using one's mind. I based the principle of the machine on the ideas of Gestalt with the collective unconscious. What if a person could connect with the mind of someone who lived centuries ago. It happens randomly in nature. For reasons I never could quite work out, the trip only lasted twenty-two hours and nineteen minutes, and the person using the machine inhabited the body of someone in the past and lived a day in history, so-to-speak.
