Projection mapping is a technology used to turn irregularly shaped objects into a display surface for projection. After the object is chosen or created, a virtual replica of the entire physical setup is created. A virtual model of the projection surface is created, and placed within a virtual environment. Coordinates need to be defined for where the object is placed in relation to the projector. Finally, the xyz orientation, position, and lens specification of the projector are adding to the virtual scene.
Video mapping first gained notoriety through guerilla advertising campaigns and video jockeys for electronic musicians. These advertising campaigns commonly used mapping techniques to project interactive scenes onto the sides of buildings. Common techniques for these performances included both 3-D mapping techniques and 3D projection to create the illusion of depth.

Late modernity (or liquid modernity) is a term that has been used to describe the condition or state of some highly developed present day societies. It regards their state as a continuation or development of modernity, rather than as a distinct new state, post-modernity.
‘Late modernity is defined by complex, global capitalist economies and a shift from state support and welfare to the privatization of services…a process fuelled by the information revolution, the capacity to move capital and information around the world instantaneously.’ Social theorists, ‘criticize adherents of postmodernity that presume the ending of the modernization process and the dawning of a new era. Contemporary modernity, they argue, rather involves a continuation or even a radicalization of the modernization process.’

Pronoia [proh-noi-uh] is a neologism that is defined as the opposite state of mind as paranoia: having the sense that there is a conspiracy that exists to help the person. It is also used to describe a philosophy that the world is set up to secretly benefit people. The writer and Electronic Frontier Foundation co-founder John Perry Barlow defined pronoia as ‘the suspicion the Universe is a conspiracy on your behalf.’ The academic journal ‘Social Problems’ published an article entitled ‘Pronoia’ by Fred H. Goldner in 1982.
According to Goldner: ‘Pronoia is the positive counterpart of paranoia. It is the delusion that others think well of one. Actions and the products of one’s efforts are thought to be well received and praised by others. Mere acquaintances are thought to be close friends; politeness and the exchange of pleasantries are taken as expressions of deep attachment and the promise of future support. Pronoia appears rooted in the social complexity and cultural ambiguity of our lives: we have become increasingly dependent on the opinions of others based on uncertain criteria.’

Duff Beer is a brand of beer that originally started as a fictional beverage on the animated series ‘The Simpsons,’ since then it has become a real brand of beer in a number of countries without permission or consent from it’s original creator, Matt Groening, and has resulted in legal battles with varying results. Groening has stated that he will not license the Duff trademark to brew an actual beer, over concern that it would encourage children to drink.
It is Homer Simpson’s beer of choice and a parody of stereotypical commercial beer: very cheaply priced, poor-quality, and advertised everywhere. The name was inspired by one-syllable beer names in the US (such as ‘Bud’). In an excerpt from his autobiography, former Guns N’ Roses bassist Duff McKagan claimed that the beer was named after him as the writers were fans of the band and he was known for his extreme alcohol consumption.

A prepared piano is a piano that has had its sound altered by placing objects (preparations) between or on the strings or on the hammers or dampers. The idea of altering an instrument’s timbre through the use of external objects has been applied to instruments other than the piano, including the guitar and harp. Richard Bunger wrote a book ‘The Well Prepared Piano’ in which he explains how John Cage prepared his pianos and even which pianos are suitable, because of the deviation of string lengths within different brands.
Bunger also clarifies why the preparations were done in such ways; in other words, which adaptation creates which sounds (harmonics obtained, timbrel effects, etc.). The timbre of the instrument changes dramatically when preparations are introduced. Much of the technique is related to the harmonic positions of the strings. For instance a preparation on 1/2 of the string length causes a different sound than on 1/3. The preparations don’t cause a random sound, as is often assumed.
