Off The Rails!
myminifactory
As a kid, I was absolutely enthralled by NITROME games - one of them in particular really stood out where you control two cactuses as they navigate through a challenging course. You can check the game out below: http://www.nitrome.com/games/offtherails/#.XaYKoJNKgWo If you're not familiar with it, don't worry - the game is just a fun little print of a couple of cactuses on a train track. The model was designed to run on HO/OO gauge wheels, which gives it an unmistakable On30 feel. If anyone decides to print it for use with O gauge tracks, be aware that it's not exactly optimized for that scale.
