Related to [this question][1], I am trying to create an elevated surface where I can put water. The surface below is made up of ladders/signs to keep the water flowing down, but still allows items (e.g., eggs) to pass through.

What is the optimal pattern for the ways in which the ladders would be laid out in, say, an 8x8 square area?
