Sometimes is usefull to run same GUI application from remote server. You can use same program like VNC, but i preferrer SSH X11 forwarding.
sudo vim /etc/ssh/ssh_config change #ForwardX11 no ForwardX11 yes
#ssh -X maksim@192.168.1.168 ssh -X <user-name>@<host-address>
Using this I can run application on my 24' screen from my laptop which have 14'screen :-)
