   Since I did not see any apparent size change in my first
test I think there should be a better way to judge perceived 
size of a modified object.  I have been thinking that using
a square grid as an infinity background may be useful for this.
So wireframe objects might interfere.  Also a stereo pair with both 
an unmodified and modified objects in the same image pair might also
help judge any distortion.  If I had a DXF file of a tera fold knot
I could set up a test with it as this object might not give the
viewers much preconceived shape information?
