How do you display a message or picture before switching off the power supply?

Is there a way to do this? I just want to display something that tells the user that it's now "safe to switch off".

Nope, because it's not safe to switch off until the Pi has fully shut down, and at that point it can't do anything.

Watch the green activity LED. At the end of the shutdown process it will blink 10 times, with the last blink longer than the others, and when that's done it's safe to switch off.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
