Optical Illusions Translated

Craik-O'Brien-Cornsweet Illusion

Compara los 2 objetos inmóviles: Dos discos oscuros centrados en dos discos ligeros grises. Al mover el ratón, arrastras una "mascara", que puede cubrir parte de los discos. ¡Cuándo ajustes de modo que el centro desenmascarado sólo muestre las manchas oscuras, notaras que el disco derecho central tiene la misma luminosidad que el externo que le rodea!

(Francisco Javier Arias Fernández)

Scint illating Grid

Si tu miras la imagen, notarás la aparición
y desaparición de puntos negros sobre las esquinas.

(Isidro Fuentes Muñoz)

Pyramid Illusion

En la imagen aparecen cuadrados sobrepuestos que se van haciendo más pequeños, y a medida que se hacen mas pequeños, sale una X que en la realidad no existe, es imaginaria, solamente sale porque es el efecto que causan todos los cuadros juntos.

Silhouette Illusion

En la imagen, aparece una bailarin a girando,mentalmente tienes que concentrarte y hacer girar la figura en la direccion opuestao. Es posiible, pero dificil.

Blur & picture content

Esto no es una ilusión óptica propia, es más un efecto físico: con un filtro borroso, esa versión carece de detalles, vemos una calavera cuando la imagen está borrosa y cuando es nítida, vemos una mujer reflejada en un espejo.

(Christian Cruz)

Optical Illusions & Visual Phenomena
