Some seniors in Guadalajara, Mexico made a cool-looking robot arm that can pick up balls and drop them — no mean feat — and it’s all run with a modified Playstation controller. The real draw, however, is the amazing video score. Imagine if they added that kind of music to everything you did in life — a swell of horns when you buy a burger, a trill of violins after taking a book back to the library. It would make life so regal.
