Someone has written a date on the gauge’s backplate: for any given physical measuring device, the motivations behind the annotation?

As new forms of digital augmentation emerge and eventually go mainstream we’re increasingly going to see traces of the digital cross over into the physical – with new guidelines, markings, colours added to the easy to recognise & augment shapes already prevalent in our towns and cities. Think service driven tagging.

The augmented reality thread here, common urban shapes here and here and my personal favourite example of augmented reality already prevalent in Japan here.
