A program I use for on-screen display.

Introduction
One day, I realized that I like the on-screen displayed volume controls and
the like on non-linux OS's, like OS X and some Windows installs. So I went
looking for a solution.
I found a partial solution in
The xosd Library. The problem was, it lacked a useful frontend.
So I wrote one.

Usage
To use onscreend, you have to have the xosd lib built and
installed. You may have to edit onscreend.c and replace the font, since
I use "Serpentine D", a very cool-looking but nonstandard font.
There are two binaries, onscreend and putfifo.
onscreend is the actual program that displays the text. You should
probably put it in your .Xclients file. putfifo is a simple
application that will attempt to write standard input to the fifo named in the
command-line. It differs from cat only in that if the fifo has no open readers,
it returns immediately.
Whenever something wants to display a message on the screen, it should use a
command like:
echo This is your message | putfifo /tmp/onscreen
If you want a single-tick slider, format your message like this:
echo \|50:This is your message | putfifo /tmp/onscreen
Or, for a volume-control-style slider, this way:
echo %50:This is your message | putfifo /tmp/onscreen
I have bindings all across my system for onscreend. I've added appropriate
lines to my hotplug configuration files, so I get notification of USB device
attaches, network connection and disconnection, and other similar things.

vtwm configuration
These are the lines I use in my vtwmrc file to control my mixer. They
will likely work in many other twm-derived window managers as well, although
I can only speak for twm and vtwm. I left out the actual button binding,
but that should be relatively straight-forward. aumix does the actual control,
so it should be obvious that it is required for these lines.
Function "show-mixer-pcm" { f.exec "echo %$(aumix -q | grep 'pcm ' | cut -d ' ' -f 2 | tr -d ','):PCM Volume | putfifo /tmp/onscreen" }
Function "show-mixer-main" { f.exec "echo %$(aumix -q | grep 'vol ' | cut -d ' ' -f 2 | tr -d ','):Main Volume | putfifo /tmp/onscreen" }
Function "mixer-up-pcm" { f.exec "aumix -w+5" f.function "show-mixer-pcm" }
Function "mixer-down-pcm" { f.exec "aumix -w-5" f.function "show-mixer-pcm" }
Function "mixer-up-main" { f.exec "aumix -v+5" f.function "show-mixer-main" }
Function "mixer-down-main" { f.exec "aumix -v-5" f.function "show-mixer-main" }
