Party time and oil slick are very similar, party time is almost like an army camouflage pattern but with bright crazy colors. Oil slick is more of pastel colors that are in a swirling pattern. There are also 3-4 variations of rainbow stamps; random rainbow, linear rainbow, splatter rainbow (stamp looks as if its been made up of small dots up close) and one more, I don't really know what to call it, it's where the stamp colors vary by the different parts of the stamp, which are usually each one solid color. There is a thread somewhere with all the different stamps Innova has made with examples.
