I love working with start up companies. There is a great vibe that goes along with entrepreneurs. I recently worked with a new ad agency, Fellow, and their startup client Canopy. Canopy has developed iPhone App's and hardware. The App adds functions to the iPhone's still and video cameras. Their sleeves have fittings on it so it can be mounted to a standard tripod head. Another sleeve plugs into the iPhone and adds buttons to the top of your iPhone. I formally traveled with a good point and shoot as well as my pro gear. Not anymore. The quality is amazing. Here is a link to my Vimeo page to see a test I did with the Canopy App and sleeve.
This picture shows one of my setups. I screw a small tripod head to the Canopy sleeve, then attached the head to a stud with a clamp. I then clamped the rig to a bolt sticking out from a old light house foundation. The driving shots were accomplished by attaching this same rig to the grill of a Jeep.
