Guinness-only QR Code

The dieline has a post about a new pint glass from Guinness with a QR code that can only be read when the glass is full of stout.  If the glass is empty or the contents are amber colour then the code is not readable.

Or, say, put a dark coaster in the empty glass.

Still, cool idea.
