Use AppleScript to Turn Your Fonts Folder into a Mini Application
The bare bones font panel built into OS X has never inspired me:

If you don’t know the font you want, there aren’t a lot of options for you to experiment with here. Fortunately, Leopard provides a better way to preview your fonts.
Open a Finder window and navigate to your Fonts folder (find it in ~/Library/Fonts). Now switch to ‘Flow View’ (select the forth button on the toolbar selector or press Cmd + 4) to see your fonts in the revolving carousel. As you scroll through your fonts you’ll see a capital ‘A’ and a lower case ‘g’ displayed representing the font set. To see the whole set, press the space bar to QuickLook the font.

Here is an AppleScript to automate the process of opening the Fonts folder and setting it to Flow View. It also hides the toolbar:
tell application "Finder"
open folder "Fonts" of folder "Library" of home
set current view of Finder window 1 to flow view
set toolbar visible of Finder window 1 to false
set bounds of Finder window 1 to {375, 239, 988, 667}
activate
end tell
And here is a short video of the mini application in action:
