Not sure how many folks play games or stuff like that but I’ve always been interested in Game Engines and the Tools to build them.

Neil Blomkamp in particular is using the Unity engine to make Sci Fi shorts (he did District 9 if you are into Scifi movies)
Anyhow, I guess this is off the wall to some extent but I found this one video and it has a railroad theme so I thought some might be interested in it:
