I see on http://www.carendt.com that the Australian model railroader known on the Internet as “Professor Klyzr” has finished his 2x4 foot H0 scale urban micro layout called “Brooklyn 3AM” to such an extent that it is now being displayed at model railroad exhibitions “down under”.
It is (IMO) a very inspiring and innovative small urban layout well worth having a look at, if you haven’t seen the pictures already.
Here is a link to the layout on carendt.com: http://www.carendt.com/scrapbook/page87/index.html
Enjoy,
