A Cubes Widget

  You may need to install one of these to build Motif version:
    sudo apt-get install libmotif-dev
    sudo apt-get install lesstif2-dev
  Then should be a simple
    configure; make

  Try resizing the puzzle.  Notice the puzzle resizes to take advantage of
  the "room" available.

  Try editing the file Cubes.ad to get a certain feature and then copying
  to $(HOME)/Cubes (where Cubes is the file name) and running xcubes
  again.  There is also a Windows port (wcubes).

  I stole many good things from the X11 "puzzle" by Don Bennett (except
  his sliding  image).  This program completes a theme with xtriangles and
  xhexagons. This program could be further generalized to do a tesseract
  the puzzle but in fact, it gets no harder than the 2-D puzzle except that
  its more tedious.

  Refer to the man page for detailed command line options and instructions
  on how to operate.

  If you want further information on puzzles, I'll be glad :-) to send
  it to you.

MATHEMATICAL STUFF USED IN CONSTRUCTION

  Assuming it is a box of i columns, j rows, and k stacks and the
  numbering starts from 1.
    Corner 1-> 1
           2-> i
           3-> i*j-i+1
           4-> i*j
           5-> i*j*k-i*j+1
           6-> i*j*k-i*j+i
           7-> i*j*k-i+1
           8-> i*j*k
    Center -> i%2 =>
           0: None
           1: ((i+1)/2)^3

    Max_Width -> i units
    Max_Height -> j units
    Max_Depth -> k units

    Start -> x=y=z=0
    Next -> n%i =>
           0: x= 0 units; y+= 1 unit
              if (y == j)
                 {y = 0 units; z+= 1 unit;}
           default: x+= 1 unit

    Same row? -> (m-1) / i == (n-1) / i
    Same column? -> ((m-1) % i == (n-1) % i) &&
                     ((m-1) / (i*j) == (n-1) / (i*j))
    Same stack? -> (m-1) % (i*j) == (n-1) % (i*j)
