Running Linux, then I guess you must know about Gnome . Unfortunately Ubuntu 11.04 is not coming up with Gnome as default any more. Nevertheless Gnome is an awesome desktop environment and I would like to elucidate on another technology Gnome 3 has come up which is Gnome shell
I guess the screenshots are breathtaking by themselves .
Any one interested in laying their hands on Gnome Shell can download it
Just type in the command prompt : sudo apt-get install gnome-shell
And to run it just call the application : gnome-shell -r
Note: Gnome shell is currently in development phase. There may be bugs or crashes. Also the functionality is not vast as of now.. Anyways , I guess its a journey worth taking!!!
