I did it for a while ~2006 using ASP.NET, although it wasn't as in-depth as this. It was kind of cool, but after a while it was easier to just use text and view it in a browser. I think it would be more useful to build a tool that helps visualize the overall structure of a program. The usefulness of such a tool would increase as the size of the program increased.
