This is a replica of the eye exam device from the film Bicentennial Man. It was originally fabricated by Adam Savage (see http://adamsavage.com/film.html) for the film and eventually also showed up on the TV show NCIS… for some reason.
At any rate, I love art deco, I love props and I love Adam Savage’s work. So this is something I’ve wanted to make a replica of for quite a while. I’ve included a couple of pictures of a finished one to show how it’s put together and the color scheme. The model is available for your personal, non-commercial use.
