I actually do use this prompt, but it results in noticeable delays in the appearance of the prompt on a single-user PII-400, so I wouldn't recommend using it on a multi-user P-100 or anything ... Look at it for ideas, rather than as a practical prompt.

A friend complained that he didn't like having a prompt that kept changing size because it had $PWD in it, so I wrote this prompt that adjusts its size to exactly the width of your term, with the working directory on the top line of two.
#!/bin/bash
# termwide prompt
# by Giles - created 2 November 98
#
# The idea here is to have the upper line of this two line prompt
# always be the width of your term. Do this by calculating the
# width of the text elements, and putting in fill as appropriate
# or right-truncating $PWD.
#
function prompt_command {
TERMWIDTH=${COLUMNS}
# Calculate the width of the prompt:
hostnam=$(echo -n $HOSTNAME | sed -e "s/[\.].*//")
# "whoami" and "pwd" include a trailing newline
usernam=$(whoami)
let usersize=$(echo -n $usernam | wc -c | tr -d " ")
newPWD="${PWD}"
let pwdsize=$(echo -n ${newPWD} | wc -c | tr -d " ")
# Add all the accessories below ...
let promptsize=$(echo -n "--(${usernam}@${hostnam})---(${PWD})--" \
| wc -c | tr -d " ")

This is probably the single most attractive (and useless) prompt I've ever created. Because many X terminal emulators don't implement cursor position save and restore, the alternative when putting a clock in the upper right corner is to anchor the cursor at the bottom of the terminal. This builds on the idea of the "termwide" prompt above, drawing a line up the right side of the screen from the prompt to the clock. A VGA font is required.
Note: There is an odd substitution in here, that may not print properly being translated from SGML to other formats: I had to substitute the screen character for \304 - I would normally have just included the sequence "\304", but it was necessary to make this substitution in this case.
#!/bin/bash
# This prompt requires a VGA font. The prompt is anchored at the bottom
# of the terminal, fills the width of the terminal, and draws a line up
# the right side of the terminal to attach itself to a clock in the upper
# right corner of the terminal.

# Calculate the width of the prompt:
hostnam=$(echo -n $HOSTNAME | sed -e "s/[\.].*//")
# "whoami" and "pwd" include a trailing newline

# The A with the umlaut over it (it will appear as a long dash if
