great way to viualize a DOM

It treats the DOM like a visual or auditory spectrum. If you click the  
bookmark link (and have JS enabled), you will see the visualization on  
the left. You can mouse over it to highlight the associated element.  
Would be really cool for something like Xopus :) or other browser  
based DOM manipulators.

best,
