Original Memo:
WHY:
The older I get, the more do I perceive myself as a phenomenon that occupies a tiny portion of space and time. And sometimes I feel connected to my past and future self with specific spaces as a medium.
Having lived in multiple cities including Seoul, New York and San Francisco, I have formed a mental pattern of associating places with specific times in my life. As I visit more places, especially those where I lived before, I sometimes feel the sensation of seeing myself from the past or the future co-existing in the same place.
Based on this sensation, I wanted to show people and memories from various times pertaining to a same space, and designed an interactive space where one can mix and match memories from different time spans as well.
WHAT:
Visitors are invited to take one or more snapshots of themselves using a time-lapse shutter control. Their images are then overlapped over time, sometimes with the ghosts of strangers who co-occupied the same space in a different time.
Using a proximity sensor, visitors are then encouraged to rewind time and see themselves occupying the same space with the ghosts of the people who existed there days ago.
