If you consider yourself as a Geek God and want to try out the Chrome OS yourself, you can download Google Chrome OS through torrents. The Chrome OS image from torrents can be run using VirtualBox from Sun.
Download Google Chrome OS Torrents
Download Google Chrome OS Torrent via TPB. GDGT also have uploaded a Google OS build themselves.
Once you are done downloading the torrent/GDGT build, read the step-by-step guide prepared by TechCrunch to install Chrome OS on your PC/Mac/Linux via the VirtualBox.
The default login to Chrome OS is your Google username and password. But my sincere suggestion is to create a dummy username on Google just for testing out the Chrome OS, so that you nullify any risk coming via torrents.
