We've got a RED ONE Digital Cinema Camera at work and the RED ARM broke, and after multiple failed attempts at repairing it, I decided to design a new arm. "CAMS" stands for "Camera Accessory Mounting System" and this is the first piece, which is meant to mount an LCD Display to a RED Camera, but you can use it with anything that uses standard 1/4" mounting hardware.There's a bit more info in this blog post: http://rasterweb.net/raster/2014/03/05/a-new-arm-part-ii/
