Siren's Call Crease Pattern
Siren's Call uses the Cluster 4 symmetry in the equilateral triangles tiling and it's a hybrid between Stars in Stars and Emergent Hexagons.
It has closed and open triangle twists on both sides of the paper, and shows a fascinating pattern of through-going bars in backlighting.
Fold straight from the grid, no precreasing required - just don't forget to keep a grid triangle in the center!
