The Japanese can now download an app to their smartphones called Internet Shrine that rewards the prayerful with free wi-fi. You place your phone in a clear, well-ventilated place with the app running. Then, you clap twice as if praying at a Shinto shrine. This activates the application. Then you go to your computer and search for a Wi-Fi network called Amaterasu, the Shinto goddess of the sun and the universe. Connect to the network and Amaterasu will give you 15 minutes of free internet access. The developers also plan to release the application under an open-source license so people everywhere can have an internet shrine tailored to their local culture.
