sorry, if my comment was a ambiguous. If you've got some more time to
exercise, it's easy to do a hardware implementation - it's called
"astable multivibrator" take a battery, two Transistors a Cap and few
Resistors,... - eg. http://en.wikipedia.org/wiki/Multivibrator - for a
more professional approach, follow the NE555 IC idea. radio-shack sells
those..

"xmms" is avail. for many linux-distros:
