Room Lens at CES?

Did anyone who when to the CES show notice if vendors were using the Argent Room Lens tweak? If so, what did it do to the sound? And, do you remember who used them?
Do not remember seeing any at the show.
I didn't see any either . . .
Look through Albert Porter's pictures on the AGON home page at the bottom. I'm sure some show these in use.
