Plan-Your-Weekend Billboards
Promotional billboard at bus stops in Norway that alerts you to skiing conditions at the Tryvann Winter Park Resort - by having the billboard start snowing.
When it snows on the mountain at the ski resort (located 15 minutes outside of Oslo), they send an SMS to the billboard and the signage starts snowing in the window area A second message stops the snow show.
