New blog

Mother_nature is back with a new blog. I don't really know what to make out of it. I looked around a bit and found four pictures. The first shows two tables with numbers. The three others each have one table labeled with C, P, and L.

Why are the first two tables full and the rest almost empty? Why are some cells highlighted? And what the hell do the letters above them stand for??? Somebody please help me out.

Update: mother_nature updated his new blog with another picture. Is there a point or does he just really like Thoreau?
