Bark painting is an Australian Aboriginal art form, involving painting on the interior of a strip of tree bark.
 This is a continuing form of artistic expression in Arnhem Land and other regions in the Top End of Australia including parts of the Kimberley region of Western Australia.
 Traditionally, bark paintings were produced for instructional and ceremonial purposes and were transient objects.
 Today, they are keenly sought after by collectors and public arts institutions.

The Archivio di Nuova Scrittura ("Archive of New Writing", "ANS") is a cultural association founded in 1988 in Milan, Italy by art collector Paolo Della Grazia.
 The archive preserves a large artistic and documentary heritage about any form of artistic expression featuring the use of both the word and the sign.
 Born from the encounter between Della Grazia and artist Ugo Carrega, in the 1990s the ANS became the main Italian research center on visual poetry, organizing exhibitions, meetings and other cultural events.
 In 1998 the Archivio di Nuova Scrittura was deposited in part at the Mart in Rovereto (library, archives and some artworks) and in part at the Museion in Bozen (artworks only).
 The artwork section of the ANS includes about 1,600 works by international artists at Mart and about 2,000 at Museion.
 The ANS archives preserve, apart from the internal archive of the association (ANS fonds), the Fraccaro-Carrega fonds, containing the papers of collector Marco Fraccaro and visual poet Ugo Carrega.
 The library section, preserved at Mart, contains more than 10,000 volumes, among them 600 artist's books and hundreds of futurist first editions, and 500 art magazines including about 100 international artist's magazines.
Performing arts are a form of art in which artists use their voices or bodies, often in relation to other objects, to convey artistic expression.
 It is different from visual arts, which is when artists use paint, canvas or various materials to create physical or static art objects.
 Performing arts include several disciplines, each performed in front of a live audience.
A medal or medallion is, strictly speaking, a small, flat, and round (at times, ovoid) piece of metal that has been sculpted, molded, cast, struck, stamped, or some way marked with an insignia, portrait, or other artistic rendering.
 A medal may be awarded to a person or organization as a form of recognition for sporting, military, scientific, cultural, academic, or various other achievements.
 Military awards and decorations are more precise terms for certain types of state decoration.
 Medals may also be created for sale to commemorate particular individuals or events, or as works of artistic expression in their own right.
 In the past, medals commissioned for an individual, typically with their portrait, were often used as a form of diplomatic or personal gift, with no sense of being an award for the conduct of the recipient.
"Space art" (also "astronomical art") is the term for a genre of modern artistic expression that strives to show the wonders of the Universe.
 Like other genres, Space Art has many facets and encompasses realism, impressionism, hardware art, sculpture, abstract imagery, even zoological art.
 Though artists have been making art with astronomical elements for a long time, the genre of Space Art itself is still in its infancy, having begun only when humanity gained the ability to look off our world and artistically depicted what we see out there.
 Whatever the stylistic path, the artist is generally attempting to communicate ideas somehow related to space, often including an appreciation of the infinite variety and vastness which surrounds us.
 In some cases, artists who consider themselves Space Artists use more than illustration and painting to communicate scientific discoveries or works depicting space, some have had the opportunity to work directly with space flight technology and scientists in attempts to expand the arts, humanities, and cultural expression relative to space exploration.
Todd Webb (September 5, 1905 – April 15, 2000) was an American photographer notable for documenting everyday life and architecture in cities such as New York City, Paris as well as from the American west.
 His photography has been compared with Harry Callahan, Berenice Abbott, Walker Evans, and the French photographer Eugène Atget.
 He traveled extensively during his long life and had important friendships with artists such as Georgia O'Keeffe, Ansel Adams and Harry Callahan.
 He photographed famous people including Dorothea Lange.
 His life was like his photos in the sense of being seemingly simple, straightforward, but revealing complexity and depth upon a closer examination.
 Capturing history, his pictures often transcend the boundary between photography and artistic expression.
A kakekotoba (掛詞 ) or pivot word is a rhetorical device used in the Japanese poetic form waka.
 This trope uses the phonetic reading of a grouping of kanji (Chinese characters) to suggest several interpretations: first on the literal level (e.g. 松, "matsu", meaning "pine tree"), then on subsidiary homophonic levels (e.g. 待つ, "matsu", meaning "to wait").
 Thus it is that many waka have pine trees waiting around for something.
 The presentation of multiple meanings inherent in a single word allows the poet a fuller range of artistic expression with an economical syllable-count.
 Such brevity is highly valued in Japanese aesthetics, where maximal meaning and reference are sought in a minimal number of syllables.
 Kakekotoba are generally written in the Japanese phonetic syllabary, hiragana, so that the ambiguous senses of the word are more immediately apparent.
