Play the movie (which lasts 1 minute) full screen and stare to the center of the image. After the movie finishes, look away (for example look to a face or to your hands). For few seconds everything you see will appear to distort.
The original idea is not mine, I have seen on the net, BUT this animation file was created by me with this C program.
Türkçe: İllüzyonu görebilmek için, videoyu tam ekranda oynatın ve şeklin merkezine odaklanın. Video bittiğinde farklı bir noktaya ( elinize ya da yüzünüze) bakın. Bir kaç saniye boyunca baktığınız her şey bozulmuş gibi görünecek.
