We have been developing a spectacle frame / sunglasses for the best part of 14 months now.
It is being made with one of the last frame makers in Britain, all hand-made, with a handful of people cutting and shaping and whittling and buffing the frame like woodworkers. Remarkable. The final drawings were, um ... drawn-up, yesterday, and this means they aren't far away at all.
Here they are, along with the most recent -- slightly thicker than the final thing -- acetate and gold prototype.
