BBC celebrates the second season of His Dark Materials with an augmented reality "portal".
Inspired by Philip Pullman’s book, the portal allows fans to tear open portrayals via their phones. As they enter the alternate world, users can take selfies and hunt for plot-based Easter eggs. The work was created by Emma Brooke and media is handled by Havas.
Last year, BBC Creative built a "breathing" billboard to promote season one of the series.
