I was shown two objects and asked
What do you see?
Mirrors - a muted gold rimmed slight old style oval mirror and a square one - again gold, brighter wider border.
Now as you look at the objects, carefully observe how your eyes move.
Oval mirror - my eyes follow the rim of the oval. Don't recall if I actually looked at the center, probably not.
Square mirror - My eye goes to the edge design, but then moves to the center seeing my reflection (it doesn't follow the rim like it did for the oval one)
