First I took one picture of the
mirrored glass ball suspended by string. That effectively provides
about 355° angle of vertical and horizontal coverage.

Then I used ptGui, the Windows graphical interface for Helmut's PanoTools,
to turn that spherical image into a "equirectangular" flatfile image.

I did a little tweaking in Photoshop, and reversed the image
(flip horizontal) to compensate for using a mirror image.

Then Helmut's PTViewer takes that image and displays the final
spherical panorama image (~190K).
