I know I've seen this somewhere before, but I can't think where, so I turn to you guys for help.   The kids and I have been making sure we've got one complete set of minifigs from each series, for the last year or two.  I don't like just displaying them on their stands - that's boring.  Instead, I'd rather get them into little dioramas, or habitats.  Nothing big - like maybe 8x8 or 10x10.  But something just big enough to make a small scene of our minifigure in their natural habitat.
