Designer: Ray Bolt
Paper: 8 pieces of 6" square paper
Diagrams: BOS Magazine No. 54
Notes: This is a 3D version of a model by Bob Neale - each piece slides in and out, changing the shape of the hole in the center; I learned it from Scott Cramer, who learned it from Tommy Stevens, who figured it out from the cover of a Korean origami book on-line someplace. It turns out that it was published in BOS Magazine No. 54.
