A fantasia on a theme, rather than an explication of the invention. Looks good, and it’s probably just as well not to explain things for lunkheads like me. But let us lunkheads try, at least! As for the invention itself, for heaven’s sake! It strikes the layman as a Rube Goldberg device, as some machine for machine’s sake. You know, it’s nice that we appreciate the beauty of things, but it’s too bad that we’re so dumb. Oh, the differences between the artists and the scientists.
