Guinness QR code

QR codes. We're pretty much over them.

They promised so much yet have basically given us little more than links to bloody websites.

Even this Guinness QR code could be shit for all I know.

But it's execution however is top notch.

It's etched on to Guinness pint glasses and only reveals itself when the glass is full of the black stuff.

Ingenious don't you think?

Hopefully it's worth scanning.
