Now, having said that, I have to ask, what would a panel like that cost commercially? The reason I ask, I’d love to get a small (maybe 12"x 12") panel done with the Freedom Central railroad’s Keystone logo. I’m not asking you, I’m just curious how much such a thing would likely cost.
I refrain from commenting on the whole Dr. Who discussion, as my interests turn more towards Starfleet. Course, that entryway would look just as cool with the Starfleet Chevron on one side and the seal of the Federation on the other?
However, as for the TARDIS… what about making it large enough in scale to be equipped with two rail axles, and using a NWSL magic carpet drive (you’d only need one) and letting it run around the layout? Just a thought. Does it have any special lighting effects? Could be easily duplicated with LEDs? Make for an awesome conversation piece at a show or convention.
Thinking about that gorgeous fish display that was shown… how good is the visibility from the front, ie the people coming to the door? Reason I ask, if there isn’t much light coming out to show off your work, you could line the edges of the glass with white LED strips (like they use for under cabinet lighting) to provide some illumination going out.
