I love when people make amazing prop replicas. This duplicate of the time circuit from Back to the Future appears to be spot on. It was made for personal use so sadly, you can’t buy it. The folks who made it realized that would bum people out so they wrote up a very helpful tutorial showing how they put all the pieces together (because they’re awesome). If you were determined, you could review it a few times and make one for your own DeLorean. Or you know, just for your nightstand. Click the link below for the how-to.
