Past Era focuses on the visualization of outdated information in the virtual world by offering the “old version” of digital technologies. Past Era a world composed of abstract geometric shapes and realistic models. Players can experience an abstract space with non-objective fragmentation, a word processing program, and an online chat session. While each of these activities took place in 2000 as well as 2021, they have changed quite a bit. Nowadays users focus on the newest trend on the internet for most of the time, and all the outdated information is eventually forgotten. In Past Era, players recover the memory of the forgotten virtual space.
