Actually, apart from camera work (worth noting that some of it resembles that seen in Vertigo (1958)), there isn't much to mark. Perhaps the most important part is how this movie depicts the process of creating art. An artists has to virtually freeze the time to make out features of a person, a place, a circumstance, or whatever else they want to devote their piece of art to.
While looking through the features, the artist chooses either beautiful and perfect, or bizarre and weird ones. Finally, these features are layered on a "canvas", perhaps undergoing through hyperbolization, metaphorization, or some other sort of transformation. I put the word "canvas" in quotes because the process applies to any form of art actually, be it paintings, literature, or, say, music.
Note that there's also a short version of the movie: Cashback (2004), however, it doesn't carry the same amount of meaning as the full one. Basically it looks simply like a short comedy. Although some people may start with the short film first and consider it as a teaser for the full version (that was my case, actually.)
