I’m trying out PictureTrail.com, which will do some cool animations on uploaded pictures. Of course, the next step would be to find 6 color sudokus that will line up along the edges.  I suspect that the easiest way to do that would be first to find a way to color the edges that satisfies the sudoku constraints on all 6 sides.  That sounds easy enough to do manually.  Then I could have my computer fill in the sides, and I already have a program that could be modified to do that.  The tacit assumption is that for any valid border (4 sides, 32 cells), there is a way to fill in the interior (49 cells).  I don’t know for a fact that that is true, but I suspect that it is.
