You are the lucky new non-tenured professor that has been hired by the Physics departement to decipher Sparky's research and keep that grant money flowing. In Sparky's now vacant office, there is a mess of picutures all about. You also know that the crystals grew in a liquid suspension and therefore don't necessarily consist of a single continuous mass. Of course, you know Sparky always took pictures of cubical areas, so you pick out pictures of the same dimensions before examining them. Each picture was created by placing the crystal on top of the film and shining a light through the crystal.
Any light striking the crystal is reflected away from the film.
The resulting picture is therefore a silohuette of the crystal projected down a particular axis. The crystal grows in a very regular way. It creates small cubical areas precisely 1x1x1 that may be adjacent to one another or that may grow separately. In essence, the crystal is a NxNxN matrix where at any coordinate in the matrix a piece of crystal may or may not reside. Each data set will be formatted according to the following description, and there will be no blank lines separating data sets.
