I have written a number of times about Memory Medallions, a coin-size, stainless steel-encased microchip for gravestone markers that tells the dead person's story in text, photos, video or audio histories, which visitors can access by pointing their Internet-enabled cell phones at it. Now the Pittsburgh Post-Gazette has an excellent story about these high tech devices.
