PyramiDOM: Spectrum DOM Analyzer

Andrea Giammarchi has created PyramiDOM a “Spectrum DOM Analyzer”. When I first saw it, and read “Spectrum” I thought I was looking at an old 48k video game, but in fact it is showing you info on the DOM:

The generated spectrum will contain every single nodeType 1 present in the document and will show via tooltip info about that node (nodeName, id if present, className if present). Moreover, it highlights somehow that node temporary changing the background (yellow one). The most wicked effect was in jQuery website itself, since it is dark, and since it is linear enough (you scroll and the spectrum is almost there where you scroll).

On the other hand, the most interesting spectrum was in Gmail, where you can spot a proper pyramid of nested divs. Each nodeName will have the same color, but for practical reasons each time this color will be different (random).

You can grab this PyramiDOM link to play.

Interesting… not sure what the applications of this are, but it looks cool nonetheless.

Cool, it helps to visualize the semantic-to-noise ratio of a page (considering that div & span are the noise).
