jason Perderabo idea is cool. but if u want ot " distribute piece of cake evenly" then you can write an additional code

n=1+rand()%4
switch(n)
{
case 1:
// use perderabo idea starting with die1 - die4

case 2:

// use perderabo idea starting with die2 - die4,die1 in circular way

case 3:
//and so on...........
}

i know its not a very pretty solution but considering your unique constraints this is the best solution i got

NAME
pnmmontage - create a montage of portable anymaps SYNOPSIS
pnmmontage [-?|-help] [-header=headerfile] [-quality=n] [-prefix=prefix] [-0|-1|-2|...|-9] pnmfile... DESCRIPTION
Packs images of differing sizes into a minimum-area composite image, optionally producing a C header file with the locations of the subim- ages within the composite image. OPTIONS
-?, -help Displays a (very) short usage message. -header Tells pnmmontage to write a C header file of the locations of the original images within the packed image. Each original image gen- erates four #defines within the packed file: xxxX, xxxY, xxxSZX, and xxxSZY, where xxx is the name of the file, converted to all uppercase. The #defines OVERALLX and OVERALLY are also produced, specifying the total size of the montage image. -prefix Tells pnmmontage to use the specified prefix on all of the #defines it generates. -quality Before attempting to place the subimages, pnmmontage will calculate a minimum possible area for the montage; this is either the total of the areas of all the subimages, or the width of the widest subimage times the height of the tallest subimage, whichever is greater. pnmmontage then initiates a problem-space search to find the best packing; if it finds a solution that is (at least) as good as the minimum area times the quality as a percent, it will break out of the search. Thus, -q 100 will find the best possible solution; however, it may take a very long time to do so. The default is -q 200. -0, -1, ... -9 These options control the quality at a higher level than -q; -0 is the worst quality (literally pick the first solution found), while -9 is the best quality (perform an exhaustive search of problem space for the absolute best packing). The higher the number, the slower the computation. The default is -5. NOTES
Using -9 is excessively slow on all but the smallest image sets. If the anymaps differ in maxvals, then pnmmontage will pick the smallest maxval which is evenly divisible by each of the maxvals of the original images. SEE ALSO
