A detailed, layer-by-layer teardown of the mobile phone and its history

Full disclosure, I wrote this. It's a detailed teardown of the smartphone and the history of its components, written to be read on the device it describes. Some layers demonstrate themselves as you scroll: the screen counts its own pixels, the touch sensor tracks your finger.

It fills a little-explored niche: I haven’t come across anything else that brings together this level of detail and (hopefully!) accessibility. I think it’s neat, I hope you do too.
