HaikuError replaces error messages with Haiku.

There is a single command to load the Haikus:

  *LoadHaikus <filename>

The file is in Messages form, with tokens formed from hexadecimal error
numbers (with FS number masked out). See the included "Haikus" file for
an example.

I forget who suggested such a thing, but I'm grateful for the idea.
