I am a fan of Lullatone, of course, and they released some alarm and ringer tones.
I like the last one, Polyrhythmic Ringer #1, the best. It reminds me of the beautiful, and really powerful, scenes from The Girl Who Leapt Through Time; the alarm/ringer builds up dramatically, while having the chimes that seem to be played by time gnomes.
I wonder if there are more, since it is #1.
