Dspatten has a train set up around the Christmas tree.
Finally, I've blogged this one before, but it deserves multiple mentions. Michael Jasper's great Frechen 2007 shows scenes from a German AFOL gathering. The figs are showing off their creations, including an Eiffel Tower, a Yellow Castle 375, several trains, R2-D2, and micro versions of MOCs that were actually on display at the real event.
