I haven't any if idea if anyone is still using the aplwrap thing David
Lamkins and I hacked together a few years ago, but I just updated it,
which mostly consisted of replacing a couple of GTK+/glib things that
had been deprecated. You can also set the foreground and background
colours now, in case you want your screen(s) to be more attention-getting.
Anyway: https://github.com/ChrisMoller/aplwrap
