What do you call the plastic bar used in grocery checkout lines? A plastic bar? A thingy in the checkout line? A divider? A cuboid? This ubiquitous neutral plastic bar doesn't have a fixed name but creates firm divisions and respected boundaries–it functions as an indicator of personal space within a public context.

Inspired by deep sea animals’ aposematic features which work to simultaneously warn and repel predators, Checkout Line Ecology is a collection of objects that reimagine the grocery checkout line as a uniquely dynamic habitat. Incorporating cast glass and silicone, Checkout Line Ecology combines bright colors and irregular movement to reimagine the checkout environment.
