Lava Folds
Ropes of cooling lava buckle into overlapping folds. A travelling compression wave moves through a broad tongue, a narrow stream or a branching fan.
About this pattern
Pāhoehoe-inspired geometry · travelling fold waves

An art-directed parametric sheet, rather than a thermal lava simulation. A smooth envelope confines the stream; travelling waves compress its cross-sections and curl their edges. The twenty-second cycle closes seamlessly.
