OK—my first image is admittedly kind of "cosmic," but I wanted to convey the ideas of writing, communication, technology, and virtually unlimited possibility. Sadly, the idea of rhetoric (my own disciplinary focus) is not directly conveyed here; probably, though, it is implied by the possibility of participating in / changing global discourse through writing and technology. From the point of view of cultural inclusion (not to mention statistical reality, at JMU), it would make sense for the hands to be those of a woman. And perhaps it would be ideal if the skin tone of the hands was tanned / light brown (are they already?).
My second image is one I created, and it’s a simple Venn diagram. Although it is simple, I’m hoping the colors—which reflect the RGB color wheel used for a lot of visual rhetoric—are eye-catching. While our three subdisciplines are peripherally inscribed in white upon their color fields, the centrally-located name of our department is inscribed in black on white, and in a larger font. The font style is intended to be crisp and narrow—to be quick and easy to read and to take up minimal width in relation to height, without visual distortion. In terms disciplinary culture, I’ve given a kind of preeminence to “technical communication” by placing it horizontally and immediately below “WRTC.” Really, that placement was necessitated by the desire to maintain design symmetry, since “writing” and “rhetoric” are more equally sized. The important thing here is the idea of subdisciplinary overlap, which implies the idea of interdisciplinarity.
