(Partially) Setting Up Chopper
Note that I set Y amplitude to be ~149 units high. I did some quick trig based on the width vs height of the viewer circle and found that to be our goal for the Y amplitude if X is 130 units.
Are we sure that the picture in the procedure for the diagonal is correct? See Fig. 7-11, the result in figure 10 seems much more like what figure 5 in the procedure is indicating.
