Google Secret Lab, Prelude

Click it and you get …nothing. The site reveals itself only if you have the proper login and if you use a network known by Google. Residues of Eval.google are found on the web, but the full content of the mystery site has never been published before.

It is supposed that Google uses this site to allow real people to keep the quality of their results high. It seems obvious that a smart company would real people for quality assurance.
