If you’re not familiar with ChromiumOS, it’s the open source version of Google’s Chrome operating system which is meant to work entirely with web applications.  Most users have been out of luck to try it out on anything other than a Chromebook.  As a result, web developer Liam McLoughlin (who in the online world goes by Hexxeh) just launched a customizable ChromiumOS version called Lime.  What drew our attention to ChromiumOS Lime is that it can be written to a USB flash drive so that you can try it out on your own laptop, netbook or PC.
