Great evolution story. Also love seeing what can be achieved by stepping outside design lines, re. centred, symmetrical UIs. Makes me want an apple watch ;)

As an aside there's a screenshot in the article showing the Hidden Valley at Glen Coe, which happens to be one of my favourite short walks in Scotland.

A less happy aside of that aside is the house at the base of the valley. I used to look at it dreamily as we drove past, always closed up, nestled by itself in a remote nook between the mountains. What an extraordinary place it would be to live. The park for the hike was only a couple of hundred metres up the road. A few years later I recognised the house in a Louis Theroux doco, when he travelled there with its owner - TV personality Jimmy Saville. Wow. And then a few years later again, after I'd returned to Australia, it came out, posthumous, that Saville was one of the UK's most prolific child and sexual predators. Horrific stuff. The name and outline of the cottage structure can actually be seen at the top of the map in the screenshot.
