Lego Art

The creative arts are often divided into more specific categories, each related to its technique, or medium, such as decorative arts, plastic arts, performing arts, or literature. Unlike scientific fields, art is one of the few subjects that are academically organized according to technique . An artistic medium is the substance or material the artistic work is made from, and may also refer to the technique used. For example, paint is a medium used in painting, and paper is a medium used in drawing.
An art form is the specific shape, or quality an artistic expression takes. The media used often influence the form. For example, the form of a sculpture must exist in space in three dimensions, and respond to gravity. The constraints and limitations of a particular medium are thus called its formal qualities. To give another example, the formal qualities of painting are the canvas texture, color, and brush texture. The formal qualities of video games are non-linearity, interactivity and virtual presence. The form of a particular work of art is determined by both the formal qualities of the media, and the intentions of the artist.
A genre is a set of conventions and styles within a particular medium. For instance, well recognized genres in film are western, horror and romantic comedy. Genres in music include death metal and trip hop. Genres in painting include still life and pastoral landscape. A particular work of art may bend or combine genres but each genre has a recognizable group of conventions, clichés and tropes. (One note: the word genre has a second older meaning within painting; genre painting was a phrase used in the 17th to 19th centuries to refer specifically to paintings of scenes of everyday life and can still be used in this way.)
The style of an artwork, artist, or movement is the distinctive method and form followed by the respective art. Any loose brushy, dripped or poured abstract painting is called expressionistic. Often a style is linked with a particular historical period, set of ideas, and particular artistic movement. So Jackson Pollock is called an Abstract Expressionist.
