I saw that my friend @Hardback made one of these, and I thought it was pretty interesting, so I decided to make my own! In general, I'm not afraid of most things, but I'm very, *very* afraid of a few select things. Failure is the fear that I have to put up with the most.
I did all the artwork of what's inside the jars by myself, though I did use references for the cobweb and theatre masks. The background is created by an AI! Go check out app.wombo.art, it's amazing. I used the prompt "Fear" with the "Dark Fantasy" filter for this. Like everyone else, I don't know who started this idea. But whoever you are, you're super creative. I love this concept.
