chomp space, for 3x19 bar, ie., 20x20x20 array
There is a sphere at [i,j,k] if this corresponds to a second player win
chomp position. [i,j,k] corresponds to a chomp bar with rows of length
k, k + j, k +j+i. Mouse controls view, and colour is constant on constant
value of k. On page load, you are looking at the L sheets for k=0 to 19
with the k=0 sheet at the back (red shperes)
and k=19 at the front (magenta spheres).
This is the L sheets from here piled up together.
