Looking at a Digital Clocks also work for me. For some reason those always seem to “bug out”, showing or hiding random lines and sometimes even showing an unreadable time.

I've noticed something similar. If I try to look at a piece of dream text, it looks all garbled. Just like how some AI art generators make text.

Except, I can't remember if my dream text look that way before I was exposed to AI art, or if my dreams were influenced by my memories of AI art text.
