Keynote has some pretty cool themes built right into the application. If you give a lot of presentations, and need to refresh your look, or if you need something a little more business-like, you may need to go elsewhere.

There are several sites available that has an archive of themes for Keynote, but the best that I have come across is KeynoteThemePark.com. Not only do they offer incredible graphics, buttons, etc., but they also offer a huge variety of cut-outs (image patterns). Below is a small example of the quality you can expect:

There are several ways to buy themes from here:
- As an individual theme
- As a set of 3 themes
- As a superset of 4 sets (a total of 12 themes)

Prices vary depending on the quantity of themes you wish to buy, as well as the type of theme you are looking for, but they are all guaranteed to look outstanding!
