Apparency Half a century ago, Stern discussed this attribute of an artistic object and called it apparency. While art is not limited to this single end, he felt that one of its two basic functions was "to create images which by clarity and harmony of form fulfill the need for vividly comprehensible appearance." In his mind, this was an essential first step toward the expression of inner meaning. Kevin Lynch, The Image of the City artmeaningimagesharmonyform
Tactical urbanism Tactical urbanism includes low-cost, temporary changes to the built environment, usually in cities, intended to improve local neighborhoods and city gathering places. Tactical urbanism is also commonly referred to as guerrilla urbanism, pop-up urbanism, city repair, or D.I.Y. urbanism. The Street Plans Collaborative defines "tactical urbanism" as an approach to urban change that features the following five characteristics: A deliberate, phased approach to instigating change; The offering of local solutions for local planning challenges; Short-term commitment and realistic expectations; Low-risks, with a possibly high reward; and The development of social capital between citizens and the building of organizational capacity between public-private institutions, non-profits, and their constituents.
