Video: A Rube Goldberg-style machine uses a powerful, focused beam of light instead of a ball

This slick commercial for Japanese high-speed optical internet service au Hikari has a pretty novel take on the Rube Goldberg Machine. Each sequence in the device is powered (or otherwise set in motion) by a single beam of light sent through magnifying glasses and mirrors to burn strings, pop balloons, and melt bits of ice.
