Itty City Blocks / IttyBlox

At a scale of 1/1,000, these beautiful little models bring famous buildings to life but can also be fitted into whole blocks or assembled to form micro-metropolises. Available on Shapeways, IttyBlox features everything from stereotypical New York town houses to world-renowned works of architecture, including a lovely rendition of the Guggenheim at a thousandth the size of the original. Illumination from below and different thicknesses of materials above combine to allow these neat buildings to light up at night as well — via Urbanist
