Fantastic idea and, judging by your past work, the implementation should be very professional too - congratulations.
I would dearly love to see a picture though, even if its just a sketch (if there is a picture, it isn't in an obvious place). The video with the shiny outline of the edges only added to the frustration of not being able to have that now! I take it a prototype must exist since you are already testing different cards? Take a photo of it please!
