What you're doing has the potential to change the quality and speed of software development. We most often end up building upon existing code and libraries. Scanning through hundreds of files and doing reference search after reference search takes up an inordinate chunk of our time. Building a mental model from flat code is inefficient and error prone. IMHO every language should support this kind visualization. With virtual/augmented reality becoming more common it's only a matter of time before such visualization and programming tools will be more widely adopted.
