A retrospective, generally, is a look back at events that took place, or works that were produced, in the past. As a noun, retrospective has specific meanings in medicine, software development, popular culture and the arts. It is applied as an adjective, synonymous with the term retroactive, to laws, standards, and awards.
Retrofuturism (adjective retrofuturistic or retrofuture) is a trend in the creative arts showing the influence of depictions of the future produced in an earlier era.If futurism is sometimes called a 'science' bent on anticipating what will come, retrofuturism is the remembering of that anticipation.. similar theme is dissatisfaction with the modern world itself. A world of high-speed air transport, computers, and space stations is (by any past standard) 'futuristic'; yet the search for alternative and perhaps more promising futures suggests a feeling that the desired or expected future has failed to materialize.
