There are different graphical filters available for each stage, such as Comic Book, Wood, etc. However, you won't be able to change filters when you first play a given level. Once you've beaten the level, you'll be able to change the filters whenever you replay it. However, this works only for that particular gameplay mode; while you might have unlocked it for Katamari Forever version of the level, you'll have to do so again for the Katamari Drive, Eternal, and Classic Modes.
