Not wanting to throw cold water on anything but there is nothing in these vids that can't be done with any flash units that have power reduction control and slave triggers and the necessary knowledge, except the fact that the power output of the units can be controlled from the camera/main flash.

These vids have been made for publicity and so are designed to give the impression that there is some kind of magic going on here, which isn't the case.

Having said that I do think the system is solid but you still need to know what you are doing.
