2. Multistable perceptual phenomena
unpredictable sequences of spontaneous subjective changes
evoked by stimuli that are too ambiguous to be recognized with one unique interpretation
visual, as well as auditory and olfactory
three characteristics: exclusivity, randomness, inevitability
usually alternate between two rival interpretations –> bistable
EXAMPLES

3. Schröder’s stairs: ambiguous figure reversible figure bistable figure
…inspired Escher:
