Hear the Google Wave
On 2/22/12 Google showed a "wavy doodle" to celebrate the 155th birthday of Heinrich Hertz. The waveform is not a sinewave. It appears to be made up of elliptical segments that are similar in size and color to the regular Google logo.
This JSyn Applet uses a custom unit generator to create the sound of the doodle.
Increase the "Variance" slider to make the waveform look more like the "wavy doodle".
