Concrete ephemerality is a project designed to capture something that was once transitory and seeks to create something concrete from it. With ever more tracking and aggregation of our digital lives, online identities that were once transient and fluid are becoming more fixed by forces outside our control. We seek to visualise what our digital identities might look like to these forces as a “fingerprint”. Concrete ephemerality is created by taking standard online identifications and merging them into a unique form.
