The IllusionForge cast
Each friend shows you one idea by how they act. Meet them all and see how the ideas fit together.
-
Skim Attention; inattentional and change blindness -
Vanish The blind spot and perceptual filling-in -
Fringe Color constancy / simultaneous contrast; context changes what you see -
Fade The afterimage / persistence-of-vision — the visual trace left after a stimulus is removed (the foundation of animation, film, and many magic tricks) -
Teeter Ambiguous / bistable figures; figure-ground reversal -
Notch The impossible figure — the figure that locally reads as coherent but globally cannot exist (Penrose triangle, Escher staircase, blivet) -
Stack The perspective trap — the geometric arrangement that misleads size and depth judgments (Müller-Lyer, Ponzo, Ebbinghaus, vanishing-point depth cues) -
Loop The perceptual loop — the recursive / endless / barber-pole motion illusion (the mechanism that makes the brain see motion that can't end) -
Notion Pareidolia; the brain finds faces and patterns that aren't there -
Cue The auditory illusion — the sound-perception mechanism (Shepard tones, McGurk effect, phantom-melody, missing-fundamental)
