In addition to main exhibits of The Street Art Museum (Saint-Petersburg, Russia) there is AR-installation working on the museum territory. Navigation signs (concrete plates on the ground with symbols) mark the spots where AR-content is available. While standing on a spot, direct your mobile phone camera at graffitis on the walls, content will appear on the screen.
Some AR-objects are interactive, try tapping on them.
