Nice. Can you explain how you've done the recursion ?

The image on the table is the previous frame of the animation: 
(frame_number-1)


#declare File_name = concat("D:\\Files\\POV-Ray\\ANI0\\PovRay", 
str(frame_number-1,-4,0), ".png")

box{<0,0,0>,<1,1,0.01> pigment{image_map{png File_name}} 
translate<-0.5,-0.5,0> scale<0.854,0.480,1>*15 rotate<90,1,0>}
