I'll try to explain what is happening as it's almost as confusing as Inception.
A digital photo is sent to the machine, which then takes another digital photo of that in real life THROUGH a pair of Ambermatic glasses and then sends it back to the person via the mobile app. Phew! This is how I imagine Instagram working in Flintstone's days.
Honestly though, it's interesting and I can see the hipsters enjoying the real world Instagram.
