A paper picture of a Taza granite grinding stone is spinning now. For 5 seconds, once it's been triggered. The circular disc also syncs with the Taza chocolate pucks next door. Lots of circles. Confidence is high. Here are some pictures.
See that "Use Your Phone" alert in the two pictures above?
Christine noticed one afternoon that some people were grabbing the actual paper image of the granite grinding stone, and twisting it.
Not good for the machinery, or the paper image of the Taza grinding stone. So a sign was requested.
