Sample Arduino pgm to emit robotic noises (squeaks, beeps,etc)?

I saw an arduino program online within the last year for emitting robotic sounds (beeps, squeaks, etc.--not words) from a piezospeaker--but forgot to save it--and can't find it again.  Has anyone seen this--or even a similar Basic Stamp program?  And if so, could you send a link?  Thanks!

Look for a tone library. My Arduino Simon game uses a tone library to create it's sounds. There are other methods that can be used as well.

Thanks...unfortunately, no luck there. I did finally find a parallax pgm at if anyone else is looking.
