Here are some photographs of a Holywar setup made from Chess
Construction Set materials. The squares are 2 inch squares of
colored posterboard. You can see piles of other posterboard tiles
laying on the table. Most of the pieces come from my large Chess
set. We used knights from David's wooden Chess set for the
Crusaders. The setup here comes from an actual game we played
together. I played white. The dice along the side were used to mark
the ranks. You should be able to make out the dots on the six sided
dice. We used a ten sided die for the seven and an eight sided die for
the eight, but it's hard to make out the numbers on these dice in the
photo. Half tiles along the white side were used to mark the
files. There is a full set of these along the white side but not along
the black side. Only the ones made with a permanent marker are showing
up well in the photos.
