Virtual graffiti: App users write on ‘walls’

California – New geosocial app Wallit digitally preserves site-specific experiences with virtual walls on which people can leave messages.

The app uses augmented reality and geolocation-based technology to enable people who are physically present at a location to leave 140-character messages on virtual walls around the world. The 700 walls, in cities that include London, Paris, Tokyo, Rome, Istanbul and San Francisco, can be read from anywhere.
