JSCity – JavaScript code visualizations using Three.js

Very interesting! JavaScript powering the visualization of JavaScript.

It's unfortunate that the author has chosen to wait with giving access to the source code, insisting that it still needs to be "cleaned up".

I can understand the reasons (in most cases it seems to be vanity), but it would often be best to just give access and clearly mark it 'work in progress'. Open source miracles may happen.

I wonder if it would be feasible to represent 'traffic' in a 3D code visualization city, representing data movement in a concurrent program. A 'car' would represent a function application such as a dynamic memory operation (there would be a heap building) or of a classes instance member, and it would transport function arguments/instructions/data from one building (class) to the next. Of course, just like in debugging, the only way to get traffic data would be to get a trace of a certain time period of a programs execution.

Of course in concurrent programming, data races can happen within these function applications as well. I can't think of a good way right now to visualize execution within in a function.

Most software starts as a small shed, and ends up as a skyscraper... but with that shed still being the foundation of the scraper.

It would be nice if that could be visualized here :)

As design patterns go, optimizing your code library so that it makes a more visually appealing virtual city seems like a bad one.
