Three modular origami octahedra made from three different kinds of rectangles (Canoe Unit 60° by me).
From left to right, the rectangles are 1:√2, square and 2:√3.

1. Three origami octahedra on a lilac background. The octahedron on the right has a triangular window on the top. The window of the middle octahedron extends onto the adjacent faces by about a quarter. The octahedron on the left has open faces: the edges dominate. From the left, the colours are blue and white, pink and purple and yellow and orange.
