I am looking for visual stimuli that produce a similar effect than the well know “Dalmatian dog illusion” (see Figure attached).

If you look briefly  at the Dalmatian dog illusion  for the first time, it looks like a pattern of meaningless black and white stains (left panel). However, once a priming cue is briefly presented (the red contour in the right panel) the representation of a Dalmatian dog in a field becomes apparent. Once “seen” this representation will remain apparent even after the priming cue is removed and can't be unseen (look at the left panel again without the red contour).

Do you know other types of visual stimuli containing a hidden object shape that never pops-out before and always pops-out after the transient presentation of a priming stimulus? 

Thank you!
