She collected the visual meeting between old and young in her photo series, Imagine Finding Me. Otsuka defines the work as “embarking on the journey to where I once belonged and at the same time becoming a tourist in my own history.” From Sploid:
Sometimes she mimics what she did as a kid, other times she’s simply crossing paths with her childhood self and there’s even a few pictures where it looks like she’s taking care of her childhood self. It’s clever photo manipulation but a few of these shots really make it look like she was there the entire time.
If anything, it is a really cool concept. To be able to see your older self interacting with the younger version is both visually interesting and clever. I could see this becoming the next logical step in the re-staged childhood photos craze that is always clogging Tumblr.
All I know for sure is that if this were a real example of time travel, you could never interact with your former self. I’ve seen Time Cop, I know what happens.
