n.udge is an interactive video installation system that uses custom software to generate a world of architecture that grows, recedes, and evolves in response to visitor presence in an exhibition space. This generative system begins with a topological map of the exhibition space surrounding it - including all existing doorways, windows, outlets, railings, vents, and/ or other unique architectural elements - and goes on to use this information to create a basic vocabulary of building blocks by which it may shift, replicate, join, grow, fold, and evolve new architectural structures. In other words, n.udge utilizes the dimensions and architectural details of the space it is situated in as the malleable, sculptural material out of which it may evolve new variations (or visions) of that space. n.udge also automates the process of populating these iterations with structural offspring that are created from the furniture and other structural elements currently housed in the exhibition space. All of these behaviors are made possible through recent advances in evolutionary programming that allow computer scientists to automate the process of creating complex environments (such as virtual cities) at almost any scale or scope.
