In the previous post, I mentioned the Varizoom Stealthy. It is a product that allows for smooth mobile videography and filming, while the operator is walking under their own power (as opposed to a dolly, crane, truck, etc.). If you recall the iconic scene in Rocky where Sylvester Stallone, as the title character, runs up the Philadelphia Art Museum steps, the film followed Rocky while an apparatus that allowed the camera operator to wear the camera was employed. The VariZoom Stealthy is a descendent of this form.
You lucky people will be seeing my attempts to use this after I receive it early this coming week!
