How to install a new Font
Under Mac OS X 10.3 or above (including the FontBook) :
Double-click the font file > "Install font" button at the bottom of the preview.
It is really that simple.
Making cool artwork using Adobe Illustrator is as easy as choosing a cool font/typeface.
You just saw an example of a font. If you would like more, just Google "free fonts" and you'll get a good list.
I use www.dafont.com. They have a nice selection of free fonts that are easy to view and download. If you are going to use the font to make money, you are supposed to pay the people who made the font, or at least donate some money if you're feeling generous.
For example, the Ford logo is a stylized script, nothing too fancy. It has two ovals around it. Although, there are some nice gradients and a 3d curvature thrown in to give it a metallic feel.
Another large company with a simple logo.
Four squares and a fairly plain font.
A good logo really need not be a huge undertaking. It does need to be readable. So keep that in mind when you have huge names that can't be fit on one or two lines easily.
