The first Google Chrome Easter Egg has been discovered. Type in about:internets into the omnibox and you’ll get your own view of the tubes themselves…
I still like Firefox 3’s Easter Egg too (type about:robots).
On a more serious not, there are a bunch of about: commands in Chrome that (like Firefox) provide additional details for technical users.
Among them is the about:histograms, stats, crash, memory and version options. Try ’em out for yourself no doubt there are a few other ‘goodies’ under the hood that have yet to be discovered.
