Are there other examples of it working? (if there were links, I couldn't see them).
There's a danger of overfitting, where a technique works for one instance (or a subset of instances), but not in general. Detecting stripes could work in general, but as a SO commenter noted, "Where's Wally" images often include spurious stripes to undermine this detection strategy for humans.
To say nothing of that one Where's Wally image consisting entirely of imperfect Wally impersonators, with one real Wally identifiable only because has the correct hat, glasses and chin.
