This type of graphic would be well-suited for analyzing data such as
slices of a silicon wafer crystal.  This would let you visualize 
successive slices so you can 'see' if there are any trends in the
data (such as a 'bad spot' in the middle of all chips, or a defect
that starts in one area, and going through the lenght of the 
crystal maybe this area shifts to the side).

The way I create this graphic is to create a custom sas/graph map
data set that contains the 25 rectangles for a slice.  I then 
use "proc gmap" to map the data/colors onto each slice, and 
save each graphic by name (using the name= option).  I then
create a custom "greplay template" with 5 windows (one for each
slice) -- but, instead of making the windows in the traditional
rectangular shape, I make them smaller on the right-hand side
(this gives the optical illusion that the right-hand side is 
farther away).  I then use "proc greplay" to draw the 5 saved
gmaps into my custom template.  

Getting the color legend was a little tricky.  If I had used 
the "proc gmap" color legend, then it would have been scrunched
and distorted like the gmaps.  Therefore I did the legend by hand
using annotate.  I then added a 6th rectangular area to my custom 
greplay template, and I have it draw my 'titles' annotated legend 
using that.
