The title "UNIX MAGIC" is arguably on a banner(1).
The wall(1) visible through the window. (On NetBSD there was also a window(1) utility.)
The peak visible through the window in the distance could be mount(1) ________.
And of course, there is a man(1) visible through the window.
The prominent display of the wizard's fingers, as in finger(1), in the foreground is probably intentional.
Having so many things hanging is probably not a coincidence.
Nor is the fact that the shell has an overflow.
The streams flowing from the tubes and from a head(1).
The object in the tar bucket appears to be composed of segments.
Arguably awk is written on what appears to be a block, as in badblocks(1).
The ring on top(1) of diff with the string/line, as in strings(1), must have some significance.
From the wizard's hat hangs something with various initials, maybe a tape, a tail(1) or a strip(1).
Perhaps the crack in "B" is supposed to mean something.
Also, there must be some significance to the question mark/ankh shaped hook on the stirrer in the shell. Maybe a it is a broken link(1).
This just shows another great thing about UNIX. They took names from common things. None of the silly names we see today, especially the ones people choose for "tech" companies.
The artist should have had the wizard pouring some buffer solution. Then the overflow would be even better.
The "lid" on the oregano, whether intentional or not, is a nice touch. https://www.etymonline.com/word/lid
