What do you do with the tops of your walls? Sure; you could put books up there but it can be pretty hard to reach. Trooper Trent solved this problem in a most geeky way but building a suspended set of train tracks for a model train to run over. That’s pretty cool.
It gets better, though. Trent modified a DeLorean mode car so that it could also run on the tracks. The result? A suspended, wall mounted, Back to the Future train set.
