The Thompson Twins Adventure is a 1984 graphic adventure game that was distributed by "Computer and Video Games" magazine as a promotional 7" flexi disc "freebie" along with its October 1984 issue (Issue 36).
 The game is based on the Thompson Twins single "Doctor!
 Doctor!
", and features the Thompson Twins band members as the protagonists.
 The unusual storage format of the game showcases an experimental technique pioneered by the London-based Flexi Records label, and places the game alongside a small handful of other games distributed on grooved disks.
 This format never became established and "The Thompson Twins Adventure" is today valued more for its nostalgic and artifactual value than for its ludological aspects which have been uniformly panned by critics.
The George D. Oakley House at 2110 Kakela Place in Honolulu, Hawaiʻ i, was built in 1929 in the English Cottage style of architecture popular in Hawaiʻ i during the 1920s and 1930s.
 This house is one of the finest of only two dozen or so extant houses of similar style in the state.
 Signature elements of the style include asymmetrical massing, a roof shaped to resemble thatch, a gable with half-timbered facade, a king post truss ceiling, diamond-shaped casement windows, decorative as well as functional wrought iron, and even a tiny window in the chimney.
 Its architect was Miles H. Gray, an engineer with the U.S. Army Quartermaster Corps.
 The basement floor of acid-stained decorative concrete is also a rare surviving example of a technique pioneered by Robert D. Lammens during the 1920s.
 The house was listed in the National Register of Historic Places in 1984.
The Missa La sol fa re mi is a musical setting of the mass by Josquin des Prez, first published in 1502.
 It is one of his most famous masses, and one of the earliest and most renowned examples of the soggetto cavato technique – the technique of deriving musical notes from the syllables of a phrase, in this case "Lascia fare mi" (Italian: "leave me alone").
Capsulorhexis or capsulorrhexis, also known as continuous curvilinear capsulorhexis (CCC), is a technique pioneered by Howard Gimbel used to remove the capsule of the lens from the eye during cataract surgery by shear and stretch forces.
 It generally refers to removal of a part of the anterior lens capsule, but in situations like a developmental cataract a part of the posterior capsule is also removed by a similar technique.
Josquin des Prez (] ; c. 1450/1455  – 27 August 1521), often referred to simply as Josquin, was a French composer of the Renaissance.
 His original name is sometimes given as Josquin Lebloitte and his later name is given under a wide variety of spellings in French, Italian, and Latin, including Iosquinus Pratensis and Iodocus a Prato .
 His motet "Illibata Dei virgo nutrix" includes an acrostic of his name, where he spelled it "Josquin des Prez".
 He was the most famous European composer between Guillaume Dufay and Giovanni Pierluigi da Palestrina, and is usually considered to be the central figure of the Franco-Flemish School.
 Josquin is widely considered by music scholars to be the first master of the high Renaissance style of polyphonic vocal music that was emerging during his lifetime.
Soggetto cavato ] is an innovative technique of Renaissance composer Josquin des Prez that was later named by the theorist Zarlino in 1558 in his "Le institutioni harmoniche" as "soggetto cavato dalle vocali di queste parole", or literally, a subject 'carved out of the vowels from these words.'
 It is an early example of a musical cryptogram.
The Missa Hercules dux Ferrariae is a setting of the Ordinary of the Mass composed by Josquin des Prez, and dedicated to Ercole d'Este I, Duke of Ferrara.
 The musical source material for the mass, the cantus firmus, is derived from the musical letters in the Duke's name, a technique called "soggetto cavato".
Reverse bluescreen is a special effects technique pioneered by John Dykstra for shooting the flying sequences in the film "Firefox".
A paraphrase mass is a musical setting of the Ordinary of the Mass that uses as its basis an elaborated version of a cantus firmus, typically chosen from plainsong or some other sacred source.
 It was a common means of mass composition from the late 15th century until the end of the 16th century, during the Renaissance period in music history, and was most frequently used by composers in the parts of western Europe which remained under the direct control of the Roman Catholic Church.
 It is distinguished from the other types of mass composition, including cantus-firmus, parody, canon, soggetto cavato, free composition, and mixtures of these techniques.
Fabel is a critical term and a dramaturgical technique pioneered by the twentieth-century German theatre practitioner Bertolt Brecht.
