Low Density Hydrangea Tiling (Shuzo Fujimoto and Peter Budai)

Paper: 24 cm square of kami (9 1/2 in)
Model: side length of 12 cm (4 3/4 in)

For demonstration purposes, I decided to fold a tiling where each tile has a different number of layers. Like this you can see the effect of adding more iterations - and I think it results in quite an interesting model visually, too!
