Adjustable Cube, compressed in one direction
This cube is a mechanical toy. Its size can be adjusted: the cube can grow or shrink by a factor of about two. It starts out as a cube with a pattern resembling a Jerusalem cross on each face. Units can then slide within each other so that the cube changes its size without any units needing to be disassembled.
Cube made from my new unit, Woven Slit Module (WSM), 4:1 paper, 36 modules.
