The Wizard's hat is labeled "su" and the huge shell that everything is mixing in is brilliant. Also note the pipes on the ceiling. This is amazing.

Oregano is still around!

That ‘Oregano’ probably belongs to the wrong decade, if not the wrong century. A thread on comp.unix.wizards suggests that it is a reference to a Berkeley developer caught crossing the US–Canada border with a bag of oregano — that was actually oregano.

"Kaffee : It was oregano, Dave. It was ten dollars' worth of oregano.

Lieutenant Dave Spradling : Yeah, but your client thought it was marijuana.

Kaffee : My client's a moron. That's not against the law.

Lieutenant Dave Spradling : Kaffee, I have people to answer to, just like you do. I'm going to charge him.

Kaffee : With what? Possession of a condiment?"

Oops. Yeah you're right. Wrong century millennium, no less!

They do mention the circuit simulator, SPICE in that same thread. But still, not this oregano for sure.

The image also has a cat.

Also a fork, a broken pipe, a boot and I guess that's a log on the right.

And the “B” container is cracked, indicating they’ve moved on from B to C, and there’s a spool of thread (process threads?) - lots to enjoy, but oregano is still a mystery.

Possibly a reference to /{usr,var}/spool.

if it is a reference, this is probably more likely than process threads, since 'threads' as a native construct were a mid/late 90s addition to unix systems

Electrical circuit simulation [1] ... didn't know about this myself either, but noticed its still available in the Ubuntu repo and installed it.

EDIT: just noticed the comment by user kps in the sibling tree - might not be the software since it is too recent to be on the poster.

above the magician, one can see a lot of pipes.
