Abstract (en)
[origin: WO9904874A1] Brain-twister (1) consists of movable elements which are arranged into the groups (2) of at least four mutually separated and mutually movable flat elements (3, 4) in the scope of 360 DEG , wherein one element of each group (2) creates a central flat element (3) and at least three orbital flat elements (4) are arranged symmetrically around this central flat element (3), wherein at least one of these orbital flat elements (4) is a part of the same number of orbital flat elements (4) of a neighbour group (2) of flat elements (3, 4) again with a central flat element (3), wherein all the groups (2) of flat elements (3, 4) create an infinite and closed chain in all directions and the chains are arranged into a shape of a ball.
