A strange, impressive, and must-be-useful-somehow-but-I-don't-know-quite-how addition to the cloud computing world: eyeOS, an entire desktop operating system accessible through an ordinary web browser.  Best of all, the server software is open source, hackable (it's written almost entirely in Javascript), and easy enough to install that we were able to get a copy up and running on waycoolprojects.com in a matter of minutes.  You can try it on their demo server or install it on your own computer, but if you'd like to try it out on waycoolprojects, send Gary or me an email and we'll make a login for you.
