Final answer:
The 'stickup men' likely inhabit worlds that are in a constant state of change, represented by different states of day and night in artistic depictions.
Step-by-step explanation:
The question pertains to the representation of different worlds as symbolized in literature or art and how the 'stickup men' may inhabit these ever-changing environments. As indicated in the references, two contrasting artistic depictions present vastly different worlds: one pulsating with imminent activity and the other closed off and solitary, capturing the world's different states during day and night. In the daytime, the world is about to stir with life and activity. Conversely, at night, it appears desolate, with stickup men potentially symbolizing those who live at odds with ordinary civil timings, alienated from mainstream society, and perhaps, engaged in criminal or solitary pursuits. The mention of 'flux worlds' suggests that these worlds are in a constant state of change, much like the shifting light from dawn to night and the activities associated with each.
