I would love to see a photo of this setup.
I just scrolled through half a dozen ATC tower tour videos on YouTube and didn't see any skewed displays, but it's possible that they 1) they tidied it up for the tour, or 2) they just didn't apply this approach in those particular sites. I'm still very interested to see this novel application.
IIRC it was a large Wacom or similar display.
