• A projector or screen in the hallway displays a video of the same time in the hallway from n days ago.

    • (n is random)
  • In places like schools, where routines are generally the same, it might be possible to see your past self.

  • Cut out only the people using background subtraction and overlay them.

  • I’m curious about how much movement is the same in school.

  • Installation at school

  • Actually, it would be interesting if two locations in the school were connected by projectors, not just the past.

  • Possible locations:

    • Lounge
    • Recessed area on the stairs
  • #might implement it.
