Many research groups have used a software city metaphor to visualize mostly-static aspects of program behavior. We intend to extend the software city into a depiction of dynamic aspects of program behavior. This talk gives a brief review of the software city metaphor and then discusses the tools necessary to import dynamic program execution behavior into a videogame-like environment, including a collection of transpilers, an old execution monitoring architecture, and a mapping of program execution events into videogame entity actions.
