Yokata.jp is a free webservice for Japanese mobile phones.
It allows its users to provide a simple feedback about any live performance (music, theater, etc.), in real-time, with the use of QR-codes.
They needed a bunch of characters to represent the diversity of their users, that they could use in their communication, mostly print and video.

I used these characters in a game experiment I am working on.
