Ishinokoe in Japanese means ‘voice of stone’ and a company with this name based in Kofu City, Japan specializes in stone tombstones. A Press Release of theirs announces a new product ‘Kuyou no mado’ which are commemoration windows with QR Codes. The idea is that when the doors of the tombstone are open a QR code is visible. When decoded it leads to a webpage on which there are images and comments in memory of the deceased. The QR code in the picture decodes as http://d-qr.net/dqrcgi/r.aspx?r=8r13eci7.
