Categories
Construction sets can be categorized according to their connection method and geometry:
- Struts of varying length that are connected by nodes are good for building space frames, and often have components that allow full rotational freedom.
- D8h (*228) nodes are used for K'Nex, Tinkertoys, Playskool Pipeworks, Cleversticks
- Ih (*532) nodes are used for Zometool
- Panels of varying sizes and shapes
- Panels of varying sizes and shapes are connected by pins or screws perpendicular to the panels, which are good for building linkages such as an Erector Set, Meccano, Merkur, Steel Tec, Lego Technic, Trix, FAC-System and Überstix
- Panels of varying sizes and shapes with flexible panels or hinges between panels such as Tog'l, Jovo.
- Building components with various methods of connection include:
- No connection: toy blocks, Anchor Stone Blocks, KEVA planks and Kapla
- Studs: Rokenbok, Lego, Coco, Rasti, Tente, Mega Bloks, fischertechnik, Playmobil, Loc Blocs, Cobi blocks, Betta Builda and Oxford
- Notches: Lincoln Logs, GIK, and Stickle bricks
- Sleeves: Capsela

Famous quotes containing the word categories:
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
“Of course I’m a black writer.... I’m not just a black writer, but categories like black writer, woman writer and Latin American writer aren’t marginal anymore. We have to acknowledge that the thing we call “literature” is more pluralistic now, just as society ought to be. The melting pot never worked. We ought to be able to accept on equal terms everybody from the Hassidim to Walter Lippmann, from the Rastafarians to Ralph Bunche.”
—Toni Morrison (b. 1931)
“All cultural change reduces itself to a difference of categories. All revolutions, whether in the sciences or world history, occur merely because spirit has changed its categories in order to understand and examine what belongs to it, in order to possess and grasp itself in a truer, deeper, more intimate and unified manner.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
