Does anyone know of a hack that changes system sounds?

[___]

And when I mean system sounds, I refer to those plain beeps when you press on menus and icons. That would be neat to have windows snapping and swooshing sounds instead of the beeps...

[*L*F*C*M*]

TechSounds Hack can change them, but it's with 'Trekkie Noises' . . . you don't get a wide selection.

AND, it doesn't work on the NX, not even with TealMaster. :(
