Pinsound have released (or will in 2 months) a motion control board to run a shaker and other devices. Its expensive at £170 but ships with a shaker for all, including WPC, so you can count it as red my TAF and TZ will be getting one. You can pre order on the site. Im a fan of their hardware, I just wish there were better sound mixes for pinsound, licensing is a real problem.
