Hey List,

I would like to let you know about Sonar GNU/Linux. It is a accessible 
distro based off of Ubuntu. Just boot the live disk and Orca will start 
to talk.  There are 2 flavors, both in 32 and 64 bit. The first is just 
called Sonar which has the gnome-classic as the default desktop. The 
other is Sonar-Gnome which is using the Gnome-shell as the default 
desktop. These are beta releases but are done functionally. The only 
thing left is the visual side of things. Oh, and these are based of of 
Ubuntu 12.04.  If you would like to download, here is the link:

Thanks and enjoy.
