And OLD idea too :-) I've already had such a prompt for the last
three years, which includes the output from the original 'smiley'-PROGRAM!
If somebody is really interested, mail me, but I'll have to fish the parts
smiley-parts out of my prompting mechanism from diverse files (It might
need a while :-)
I also have a mechanism to 'sometimes' print system-information
before my promts, because I supervise more than one system...
AND I have a problem with LINUX-console color-prompts which
on being redrawn by (eg.: ^L at the top of the screen)
loose a blank and then edit of by one (no idea where this comes from).
Any ideas how %{...ansi-color-sequences...} might differ in length
between the first time it is done (_typed_) and all the latter times
when it's _redrawn_ to be edited ?

The only phenomenon I've seen that behaves like that is nothing to
do with escape sequences in the prompt. In zsh version up to 3.1.2,
if the `correct' length of the prompt changes -- e.g., if you have
the corrent directory in the prompt and then change directory -- then
ZLE can think the prompt has changed length without actually changing
what's on the screen. Could that be happening here? (This bug is fixed
in 3.1.2-zefram3.)
If that's not it, could you post your prompt setting please?

Very cool! I think it's about time I posted my BPFH :-)
Any suggestions for improving it welcome.

Well if it were possible to display a small(very small)bitmap
or xwindows bitmap file of a tachometer with a dial that reflects
the load. This would require of course several bitmaps stored
on the system. Each of the bitmaps would reflect a different
load(state). The higher the needle is on the tachometer the
higher the load on the system would be. Hope that is clear.

It is clear. And it is possible. But it contradicts the purpose of a shell.
Use "xload" instead!
