We ourselves and everything around us would be that evidence...it's finding out if everything is made up of cellular automata that's the hard part.
Or, more generally, some superimposed versions of me partially overlapping, as can be seen with those overlapping Es in the original article.
Maybe.

Maybe - it depends on the complexity of not just you but everything around you. There may be billions of similar yous around you, with some variation based on their history, but it's not close enough 'you' for your arbitrary definition.
I guess what I'm saying is, it really depends on how it all works. The interactions of different cellular automata can still give rise to incredible complexity that might make identical yous very difficult or impossible. Twins have similar circumstances to a high degree but even they can be different physically and are always different experimentally.
It's complicated.
Also look into fractals, since they are self similar.
