Yes, what we couldn't do with unlimited supplies of time and money
The plan at the moment is to do a shadow box styled diorama of downtown Osaka and the Osaka Loop Line. I want to use NCE's LED programmable lighting system to have it cycle through the various times of day. I think that will make a nice effect.
HO scale is small enough for me and its going to be difficult for me as I have some vision loss. Could not imagine doing T scal. Good luck to ya and its going to be interesting to see your layout.
