The Mouse's Tale in LaTeX
This example from section three of the LaTeX verse package documentation demonstrates an ambitious use of \indentpattern to create a striking visual effect. In this case it is defined to recreate the famous typesetting of the original Mouse's Tale as it appeared in print.
Background: "The Mouse's Tale" is a poem by Lewis Carroll involving a 'quadruple pun' which appears in his novel Alice's Adventures in Wonderland. It uses typesetting style to create the final pun (it is a mouse's tale typeset in the shape of a mouse's tail).
For more details see the poem's Wikipedia entry.
