Fossils from the Future is the title of a series of works by Seitaro Yamazaki. The series pursues the characteristics of “symbols” in the consumer society, which have been prevailing since late 20th century until today, through the aspect of “time”. The series consist of casting sand and transparent acrylic resin and the 3D printing modeling data. Among the three support components of the work, casting sand and acrylic resin have been respectively and constantly undergoing chemical transformation process through interactions with their surrounding environment in their own time axes. Thus, the combination of timelines of the three support media is always different. That said, the modeling data can produce something “extremely similar” to the acrylic resin part as a replacement.
