An 128x128 empty lattice [Un treillis carré 128x128].
A random medium is defined using a 128x128 square lattice:
Some of its sites are empty -black- and some are occupied -grey or white-.
Here is one such medium with 39.441% of empty sites.
A "liquid" -red- is poured using the only empty site -black- on the top line of the preceding picture.
It moves from empty sites to empty sites using the 8-connexity {East,North-East,North,North-West,West,South-West,South,South-East}:
But it cannot reach the bottom of the medium due to two occupied sites -white-:
These two occupied sites -white- are emptied:
Then the "liquid" -red and then green- can reach the bottom of the medium:
