There are a few tweaks available. To display the dream: xcowsay --monitor=0 -d </path/to/image> I had to define the monitor or it would display on the second one which is switched off most of the time. You can switch out the cow image for a custom one, or display a thought bubble instead of a speech bubble. I made a config file at ~/.config/xcowsayrc at_x=120 at_y=20 display_time=30000 cow_size=large  

🤣

Have you updated it lately ? 🫣

Hard to believe I never heard of this one before. Basically cowsay for X. It's in Debian repo. https://www.doof.me.uk/xcowsay/   Includes xcowfortune to display messages from fortune to energise your day:   You can even display dream images:     😉😎 It's one of those slow tinkering aimlessly on the computer days. 🤣
