These book covers were created for the episode Program as if it were part of a collection of graphic novels/comics that made up the Animatrix series.
For the first and third option, the graphics hint to the final scene where Cis makes her final stance against Duo. The red and black background implies the sky, whereas the shape of the circle hints to the moon. The colour pallet was kept to a minimum such as in the animation but the red was specifically used to reference the blood spilt.
The second option was designed to be simple with a focus on the character and typography.
