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.

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.

Two modular origami cubes made from 1:√2 rectangles and squares (Canoe Unit 90° by me).

Two origami cubes on a lilac background. Each is made from six units.
The cube on the right has two opposite vertices missing, as well as parts of the adjacent faces. The missing parts of the adjacent faces are larger on the cube on the left.
The colours of the left cube are red and white; the right cube is red and blue.

I tried to model these origami as transformation between cube and octahedron in Geogebra, but ended up with this instead
