Did you see the train stop and the "doors" open up and the passenger walk out. Uses a mini tv screen! Translation is that it stops, and the door opens, and the train will not leave the station until the passenger gets off.
Imagine all the things you could do with these tiny screens. Showing people moving in the backgrounds of buildings and such. I would suppose, you could theoretically, build a tall city building, with 4 big screens turned on its side, and have something going on in each window(shots of people and things divided up on the video itself, think opening of Brady Bunch but with wider view)
Or how about a whole factory with something going on in every window!

But... that's not Z-scale... is it.

No....but this is something new, and could be applied to Z scale. Perhaps there is even more potential to do things like this in Z scale. I always check out what the other guys are doing.And somtimes the Z people will do it better.

And it is about a hobby show, where there is Z scale, and Z scale products, and tools and paint and supplies, and electronics ...
