Tangramoids are families of 3D objects introduced in [1]. One of these objects, called here the Closed Tangramoid, or simply Tangramoid, has recently been understood as a constant volume morphing of a regular octahedron and has been proven to be a polyhedron [3] in a sense due to Buekenhout [4]. Its plastic features allowing it to be considered as a dynamic sculpture are revisited in this short communication together with technological information on new projects.
