I've been tempted to make one by taking something long and rigid like
aircraft honeycomb from Boeing surplus and
hinging it at one end and moving the other end; up and down with a
small stepper motor with and eccentric on the shaft at the other end.
then I could find the amplitude I wanted somewhere on the "rigid
board" and the frequency would be controlled by the motor. A basic
stamp could do the job.
