Retrophagísta, The Retrophagists, Retrophagy.
An imaginary (currently) art movement that uses the deliberate and conscious consumption, rumination, recombination and regurgitation of the past to create the future and the new.

A positive counterpoint to the negative, expensive ugliness of the cocaine decision that is Retromania. That just mines the past out of a fake hip nostalgia or cynically recapitulates the past for profit without adding anything new except context.
