Thank you for your inquiry again. It is no problem for me to expand further.
The thing that you are actually missing, is that before getting to know the tech, my designing work (along with the others Designers' work) revolved around general stuff. Blog article banners & announcement images to name a few, which had nothing to do with the mechanisms of the technology. But now, after having seen the technology, we are capable of making graphical visualizations of it, so as to bring awareness to the market for what we stand for and what is that new and revolutionary we have been speaking about all this time. In no way we could achieve that before.

I hope I have helped you a little better now why it was critical for the Graphics Dept.to have its Designers under an NDA agreement.
