The present invention relates to a kit element, in particular wall and/or ceiling and/or roof panels, for detachable and non-destructive joining together, i.e. with at least one kit element of the same type, comprising at least one base element, in particular a wall and/or ceiling and/or roof panel, and at least one connecting system for detachable and non-destructive joining together, i.e. with at least one kit element of the same type, wherein the connecting system and/or connecting rails and/or connecting clips are formed by means of a plug-in system with a hook-and-loop fastener, a rice tape or a plug-in tape, so that two base elements can be connected to one another in a non-destructive manner.

In a first aspect, a construction toy element is provided and includes a body and a first circumferential row of arms extending from the body. The body has an axis, and has a first axial end and a second axial end. A first circumferential row of arms extends from the body. Each arm includes a root end and a free end, and has a first connecting member thereon that is configured for connecting the construction toy element to another construction toy element. The root end projects from the body in a direction that is angled towards one of the first and second axial ends relative to a normal direction to a surface of the body.

A construction set consisting of a sequence of subsets of mating blocks each subset having blocks of a smaller size than the preceding subset, all blocks being of the same general shape and enabling the construction of naturally occurring shapes such as fractal shapes. Each block has an attachment site to the next larger size blocks and at least two attachment sites to blocks of the next smaller size. The blocks can attach to each other by a variety of means including pin and hole pairs or magnets.

Smart toys may comprise toy blocks or other shapes which may communicate electronically with one another and provide information regarding the toys or how they relate. For example, a user may arrange letter or number blocks to form words or mathematical equations, and smart toys may recite the resulting word or answer through a built-in speaker. Smart toys may contain internal electronics which allow the smart toys to operate and communicate with one another without the need for additional devices such as a mat or board, for example.
