Featured in this gallery are the illusions:
Rotating Snakes – Circular snakes appear to rotate ‘spontaneously’.
Rotating Rays – The outer ring of rays appears to rotate clockwise while the inner one counterclockwise.
The autumn color swamp – The inset appears to move.
Opposite Rings – The right ring appears to rotate clockwise while the left one counterclockwise.
Visual Phantoms – They appear to expand laterally. This is the central drift illusion
Rollers – It appears to rotate without effort. On the other hand, they appear to rotate in the opposite direction when observers see this image keeping blinking.
Primrose’s Field – This checkered background consists of squares but appears to wave. In addition, this figure also shows a waving motion illusion.
