The video shows a scale model being hand made and sculpted. It is then scanned and turned into a fully functioning prototype with the ability to measure the products performance and facilitate ongoing formative evaluation and testing.
Precise craftsmanship. Relentless refinement. The uncompromising pursuit of perfection. It’s funny how all of these high aspirations can be condensed and expressed in the simple act of sanding down a block of wood. Throw in a nicely sharpened pencil and an earnest-looking designer, and you have the makings of basically every Apple or HTC design video ever made. Those tech companies have been following the example set by watchmakers, who have emphasized the artisanal, handcrafted nature of their products for decades.
