Visited your website.(3AM!)? Found it very informative and entertaining. I left a reply on your blog.
Australia is a beautiful area.. Been there once.... Sydney, Melbourne and Brisbane. Great memories.
Love the idea of small micro layouts as you did and connecting them together. Could you go into a little more about how your connect them up, (aligning and wiring?)
I have an idea for a small n scale layout across a desk area, consisting of 2 2'x4' modules. When needed to be stored one would sit over the top of the other and nest nicely to create a 2'x4' box, keeping the layout dust free when not in use. The backdrops would serve to form the shape of the box. Structural material to be determined...
