Yes, that was my PM - I had no idea what tile or puc boards were... I see what they do but still don't know what they are unless it's really the hockey glass Google found for me.
I do a copy, flip vertical on a new layer and move opacity to a low percentage to get the same effect. The tile would make it easier though if the image proves difficult to line up on the vertically flipped layer.
See the post where I posted the BTS, the model is standing on it. It's basically a 4x8 sheet of what's used to make shower walls. White and reflective.
