🏞️ Toy-Brick Landscape Diorama: Sculpt Rivers, Waterfalls and Bridges

Sculpt a brick-built valley, let a shallow-water river find its way down, build waterfalls, weirs, arch and timber bridges, a watermill and windmills, and flood-test them. Real Manning, weir and wheel-power maths with live readouts.
