My portfolio 8 haiku is simple. I'm not practiced in poetry so I just made mine serviceable. In hindsight I'd replace the dashes with something that creates less of a break.

Fixers come at noon

Fourth of July; red—white—blue

Text books wearing suits

The first line is meant to point towards Hall's claim that ideology tries to "fix" meaning in order to control understanding. Its supposed to lay down a unwelcoming precedent for the "fixers" because the idea of their goal is unsettling. 

The second line uses the image of patriotism, specifically the colors of Independence Day, as a concrete example of representation. Dozens of countries have the same three colors on their banner and each color means something specifically. Meaning can be manipulated.

The final line is the description of the "fixers," which can be said to be ideologies with the intent of fixing meaning. I called them textbooks because they want to instill concrete meaning and generally function from a single ideological viewpoint.
