Watch out, Instagram: new Polaroid app brings a nostalgic classic to your phone

Reverence for the original brand inspired two San Francisco-based Brits to bring back the magic with a modern twist: 3D moving images

Before everyone had a digital camera tucked inside their mobile phone, before the duck-faced selfies and sepia-toned filters of Instagram, before Flickr and Periscope and Snapchat, there was Polaroid.

From 1948 to the early 2000s, that name was synonymous with "instant visual gratification". Wait 60 seconds, and the photo you just snapped would appear magically before your eyes.
