 Many of her works are representations of words in which certain letters have been juxtaposed or rendered in different colors or scales in order to reveal hidden messages or to draw attention to the relationship between language and meaning.These features of Rosen's style can be seen in "Untitled Grid" at the Indianapolis Museum of Art and in The Whitney Museum of American Art's "Spare Parts".In some works, language becomes structure, "with words and letterforms functioning as building blocks, and where, through unusual typographic arrangements, words and phrases can embody the thing they are describing".
