I saw a link to this stuff on Cameron Reilly’s blog. Its a 2D visualisation of the DOM structure of my homepage. Each of the different colours represents a different category of HTML element. As you can see my blog template really is tag soup (but I suspect that it isn’t the worst out there).
The Java applet uses a particle physics library to do all the hard work so all the front end code as to do is render the object graph. I’d love to see this library ported to .NET. I thought I might be able to get the source and compile it under J# as a first pass, but it doesn’t seem to be available.
