New video, on mechanisms that illustrate the duality between the cube and the octahedron! Here's one of them: a linkage with fabric panels designed by @sabetta.

@henryseg The geared mechanism is my favourite.

@henryseg @sabetta there must be a way to use this design as an approximately-infinite pocket contraption...

@henryseg @sabetta Nice! I wonder if a continuous transformation is possible for spherical tilings. Maybe something with sliding, extending arcs & cables. Not sure if there's a length-invariant to be found for the cables though. https://github.com/brainsmoke/geometry/blob/main/spherical/2tri1penta_size_ratio.scad
