Falling Down Stairs Optical Illusion is one of those creepy and some what morbid warning optical illusions much like the drowned kid illusion.  The lady at the bottom of the stairs looks very realistic and im sure has startled many shoppers approaching the escalator. High resolution stickers like this the walk into glass ad or the anti drinking and driving ad can make some great 3D images that look very realistic.
