Keith Rocka Knittel: "Many-worlds Interpretation," 2009 (video still)
For this video piece, I filmed myself on two separate occasions dancing for 45 minutes straight to a mix tape by DJ Red Alert from 1988. Then I superimposed the two videos onto one background. And then, I isolated a series of animated freeze-frames, capturing parallel moments that had occurred simultaneously.
I once saw a documentary that illustrated the theory of parallel universes with a good animation of a cat experiencing two outcomes at once, alive and dead, dead and alive. Somehow, it wasn't as sad as it sounds.
