Three worlds from the newest engines

The Burgers Shore, the Forge Bridges and the Certificate Wall: fluidz, forge and edgecert as ground, each from the air and on foot, with a Go there on every picture.

The Burgers Shore from the air at dusk. The Burgers equation alive as ground: fluidz's integer Lax–Wendroff lattice at the step the hour chooses (dusk is step 116 of 154, near the wave's blow-up), tiled every 256 columns with the lanes climbing inland, so the sea cuts bays into the troughs, headlands stand on the crests and the scarp on their lee side is as sharp as the day is late. The same integers on every machine: the wave's whole run is in the fixture (sitoolz.shores, 303,401 values identical between Python and JavaScript).

On the Burgers Shore at dusk, a hovercraft world: the scarp ahead is the steepened wave's front, the bay behind is a trough. Come back at dawn and the same shore is a gentle sine.

The Forge Bridges from the air. The gap valley with its bridges: the ground falls with the distance to the nearest prime, every twin-prime pair raises two piers and a deck between them out to the lane the block's jumping champion decides (6, in this region), and every record gap of the block is cut as a gorge between its primes (46 at 2,600,977, 56 at 2,602,793, 76 at 2,603,143). The same sieve as the Prime Rails, computed independently by sitoolz.forge and checked against it.

A bridge at a twin-prime pair seen from a helicopter: two piers at p−2 and p, the deck at p−1 across the lanes out to the champion's lane. Land on the deck and walk it; the prizes stand on the piers by the lane rule.

The Certificate Wall from the air. Rule 30's edge as a wall with a certificate behind every course: course J reads the J-bit pattern of the edge at the column, stands solid where sitoolz.edgecert certifies the pattern reachable, at a height set by the period of bit J−1, and is cut to the break bit where it is not. The colour bands are the period tables themselves (grass p = 0, forest to p = 2, rock to p = 5, snow from p = 6); a lane of sand runs between courses.

Along the wall on foot, the low courses beside you and the high ones stepping up behind: every course that stands here was verified by lookups and XORs alone, no search, no oracle. A jetpack takes the courses one at a time.
