Smallest Souvenir Building?

OK, so you thought my recent post about building replicas on the head of a pin were small. Scott D. found information about a souvenir building which is even smaller. Small, as in microscopic. Swinburne University of Technology's Center for Micro-Photonics has constructed a model of the Sydney Opera House that is about half the diameter of a human hair. With dimensions of 64 x 38 x 41 micrometers, which is more than a million times smaller than the real Sydney structure, the model was built from a hybrid material of glass and polymer by firing intense laser light into the matter in a liquid state to create what to the human eye appears as an almost imperceptible dot. It took 14 years to construct Australia’s iconic Sydney Opera House, but it took only about three hours for Australian scientists to fabricate a micrometer-sized model of the building.
