Catacomb shelf

1asset skull_shelf "Catacomb shelf" complexity=4
2// a catacomb wall section to stand against a wall: three deep stone shelves stacked with long bones,
3// a row of skulls on each, pillars between, a cornice on top, candles guttering in two of the
4// niches. On some seeds a skull perched on the cornice is not quite dead: its eyes glow and its jaw chatters. Its back
5// is at z = 0 and it faces +z.
