Hawk's blog gives a larger view of the left-hand panel.
There is also a photo of Hawk's sketchbook from this strip.

HawkX speaks:
Fred gave me total freedom to do whatever I want on the left side of the comic. =)

HawkX speaks:
Keep in mind, the drawings on the left were not in script. Fred told me to draw anything I want and have fun with it.

Piro speaks:
