What else might this Snapchat feature be used for?

I came across this pretty cool Snapchat feature the other day on Twitter. Basically, if you point your Snapchat camera at the logo on the side of the Spectacles glasses pack, it turns into a secret filter. QR codes eat your heart out!

If this feature can be implemented in an Augmented Reality context then just imagine the possibilities! This backs up the Benedict Evans line of thinking of the camera being a new input device rather than simply a facilitator for our photo albums. Maybe the bet on Snap making it as a ‘camera company’ rather than a social media company mightn’t be such an absurd one after all.
