I am currently trying to create a set of graphics with a certain
step along the edges. Using a square tile, I want to rotate the
camera, in ortho view, so that the tile will look like this:

000000000011110000000000
000000001111111100000000
000000111111111111000000
000011111111111111110000
001111111111111111111100
001111111111111111111100
000011111111111111110000
000000111111111111000000
000000001111111100000000
000000000011110000000000

As you can see, this would allow for a perfect fit between the tiles.
Unfortunately, after many tries, I have been unable to get this done.
If anyone can help me get the right camera settings, I would be
thankful indeed :-)

  Did you try with a 'rotate' command at the end of the camera block?

I've been trying just that, unfortunately, it seems I can't find just the
right angle. Also, I made a mistake in the above diagram. One of the middle
lines ought to be removed, as such:

000000000011110000000000
000000001111111100000000
000000111111111111000000
000011111111111111110000
001111111111111111111100
000011111111111111110000
000000111111111111000000
000000001111111100000000
000000000011110000000000

These are my current camera settings:

camera {
  orthographic
  location <0,0,1>
  look_at  <0,0,0>
  right 1*x
  up 1*y
  rotate <52, 0, 45>
}

I've only been rotating the first number, and the closest I got so far
was as the first diagram was, but after I realized my mistake, I kept
changing
the rotation, with no luck.

I have no experience with ortho cameras, so don't shoot me if this 
doesn't work, but maybe you want to try:

camera {
  orthographic
  location <0,1,0>  // change the y value to be higher if you want a
      //picture from farther away
  look_at  <0,0,0>
  right 1*x
  up 1*y
  rotate <0,45,0>
}

Maybe it works?

Just my two cents.
