I made some new ringtones. I love the sound of old phones so the first 3 are based on the old analog bakelite phone rings. The next 2 are submarine sonar sounds. The last is from the Tokyo metro system (where they have a different audio motif for every station so you don't have to look at the signs).
I'm fascinated with why we're so keen to use old ring tones on new phones. It seems to soften the shock of new technology, to help us enjoy a smooth transition to strange new things.
