Wht not take a trip to those War games places (Games workshop) i think.
i was walking past on in bluewater the other day and they had some giant world thing they were playing on that looked pretty realistic.
Couldnt actualy bring myself to go in as the people in there were extremely "nerdy" and far to many men thinkig they were realy from the matrix! lol.
but im sure thru the window i saw supplies for building diorama stuff.
