Unusual opening credits

Saw this fascinating Pre-Code flick at MoMA this evening. Really enjoyed it, and I was especially taken with the clever opening credits: the title, cast and crew names, and everything else, are all written in sand on a beach. As the waves roll up, the lettering is wiped away, and the camera pans over to the next set of credits. And there's no music at all, just the sound of the waves. Nice! And it sets the tone for what follows, lots of interesting camerawork, not stilted like so many early talkies.
