There was a yahoo group with guys building what they call T Trak modules, that are very small table top modules. But what I am getting at is that if John Cubbin is making so may diorama's, that maybe he can come up with a standard where they can all be connected together and trains ran.
What I think would be cool is to use them to make small Youtube videos. You cna have one shot of a train entering a module, then from the other side another shot leaving the module, and so on. then have a train of enpties coming back from the other direction. Lots of fun possibilities, and on such superdetailed diorama modules, it would be hard to tell what scale iti is.
