So much for portability 8-/

Works on Suse, Windows XP and 7, though.

In Windows printing CTRL-G works from the command line but doesn't
work in the GUI.  AWT.Toolkit.Beep() works in both.

I don't know why that guy advised against it. Many games have been
written with Java. Why not go with your original idea and have some
fun. Take a break from your normal work.

This works great on my machine (Ubuntu 64 bit) and over 5 years old
Audigy sound card:

Years ago I created a toy two-channel tone generator application in Java
with sliders for frequency, volume and phase shift.  The phase shift was
fun because it could cause an unsettling feeling to innocent passers-by.
;)

Anyway, here you can find a stripped-down version that generates a short
single-channel 600Hz tone:
