Abstract: A synchronised movement apparatus comprises a plurality of polyhedron blocks arranged in a first configuration, wherein adjacent blocks have a connection therebetween that allows symmetrical rotation of the adjacent blocks relative to each other so as to transform the arrangement of blocks into a second configuration.

Abstract: A multi-dimensional structure 100 is disclosed herein. In a first embodiment, the multi-dimensional structure is configurable as a Pentachoron structure 101 having a plurality of independent geometric structures 200,300,400. Each geometric structure is defined by a number of vertices A1,A2,B1,B2,C1,C2,D1,D2,E1,E2 cooperating with respective elongate members 202,302,402. The multi-dimensional structure 100 also comprises a plurality of structural vertices A1+A2, B1+B2, C1+C2, D1+D2, E1+E2, with each structural vertex comprising at least two vertices A1,A2,B1,B2,C1,C2,D1,D2,E1,E2 from respective geometric structures 200,300,400 movably connected together.
