Working at an architecture firm I get to meet a lot of people and see a lot of things.  One of the 'neatest' things I get to see is model building, from time to time I get to chat and see Mark Gawor for GRG Group Inc work on his tiny models (sometimes pretty big even for tiny!).  They may be small models of building but they have big detail. It truly is amazing to me.  Here's on of Mark's images.  Check out his site!
