I think 45 degrees is as close as you can come without overlapping. This posed a significant difficulty passing through Photoshop 7. I think sets in between at and total overlapping of the Light Control Sphere may not be lucrative. I just got some .PYs from Ockham today, I'll be going over them tomorrow. I know I forgot to mention this before, but the light set generator I mentioned in post#21 has a rhyme and reason to it. It only generates lights of a power. That is to say sets with 1(11,) 4(22,) 9(33,) 16(44,) etc. = )
