Better Looking Emacs

To change Emacs color theme, first install emacs-goodies-el by typing
apt-get install emacs-goodies-el

To choose and try, run emacs and type
M-x color-theme-select

It will open a list of color theme.

To change the fonts, you have to install the emacs-snapshot, and use it as the default emacs afterwards.

Then:

echo "Emacs.font: Monospace-11" > .Xresources
xrdb -merge ~/.Xresources

Or:
emacs-snapshot --font "Comic Sans MS-10" SOMETHING
other very nice fonts:
--font "Cortoba-12"
--font "Purisa-10"
