iDent Card (Patreon)

A piece of incidental art for Zero Day. This card will give you access to the planet Boink. 

I actually posted this to the Discord a few days back with a cryptic note attached to it:

"In this image there are at least three in-jokes. Two of them are related to the same thing. Can you figure out what they are?"

So far, two people on there have guessed, and neither got it right. Let's see if any of you folks can do better. 

One of the in-jokes may be regional, though. So unless you've lived in the northeast of the United States, you may not get it. I'll reveal the answers after giving you all some time to mull it over.
