In another room, there were assorted optical illusions and sound or frequency tricks. One used angles and false optical cues, in conjuction with the two-dimensionality of a camera, to make people appear different sizes on a screen. Roz became far taller than she has been before, while Teddy became far smaller.
Roz and I did this. (Roz is a girl.) We did it twice, actually, to see if the effect was different depending which side we sat on. Once I wore glasses and once I did not. The effect was bizarre. Actual, I might want to use the word 'uncanny,' because it was both familiar and unfamiliar. I could recognize myself in the reflection and I could recognize Roz. The strangest part was in the eyes and the brow, which blended most. Also, when Roz moved her mouth to speak, it seemed as though her teeth appeared and disappeared from my mouth. As we played with the levels, she said it looked at one point as though she was wearing glasses and had my ears poking out from her own (our heads are different sizes). I which we had a picture of it, but, alas, I didn't think to get one. Ted and Jon did it, and Ted said they looked like a monkey.
At the end we saw an IMAX movie about the Alps. Not much to say there. We also meandered through the gift shop, but bought nothing.
