I created this illustration to show the differences between several 
types of graphical projection. I then created the arrows and angle 
measurements in GeoGebra using the 2D coordinates returned by my new 
"Get_Screen_XY" macro (see the "screen.inc" thread in p.b.s-f). Finally, 
I merged all six images into a single image using the "Contact Sheet" 
tool in XnView.

Looks good, and it's a handy chart to have. I may print this one out and 
keep a copy by my monitor. :D
