Some of my favorite movies is Back to the Future 1-3. There is something about time travel and all the intricacies and opportunities that may arise. The time machine in the films is a DeLorean DMC-12, I remember that I thought the car was really cool so what better than a tribute to a classic time machine and car.
Art prints, t-shirt and other Products are availble in my Redbubble shop.
Fun facts, in the earlys drafts of the film the time machine would be connected to a refrigerator instead of a DeLorean. It is said that the proposal was scrapped due to Steven Spielberg amongst others did not want the children to get ideas about stepping into the refrigerator.
