Looking at Minecraft from a personal perspective and the anthropological outlook for creative virtual worlds and online media. Notch’s work on this product has generated a much larger space than anyone ever expected; dynamically generated worlds, entire servers offering space for sometimes 150 people at once, the ability to create and save. All guided by a simple set of rules and underlying code that evolves from already existing online communities and adds an aspect of creation using a limited number of virtual blocks to general extremely complex visual and social structures.
