To battle the strong Pavlovian response I experienced to other peoples' phones, and because I wanted sounds that were pleasing, informative... and short, I designed a series of interface sounds and ringtones now available on iTunes (mobile link only).
Chicken Dream Alarm* is a transitional alarm that starts in the woods and transitions to the sounds of New York City playgrounds. Lama's Alarm (iTunes link for mobile devices)* is a favorite of friends, most all who use GS sounds!
"Ringtones are sandboxed by Apple. That means you can only click on the above links on your iOS device. They will not work on the desktop. Because Apple."
