Moving Ship Illusion

is this sailing ship really moving?

whole image is stationary i.e. static JPG, but when you focus on the sailboat, it seems moving as if it sailing on the sea

It's not an animated picture ..... rather the colors and position of those dots fools you into seeing the ship swaying among the waves.

Also Watch :
rocket launching illusion, another cool moving illusion.

Why those dots make the ship appear as though it's moving? ..... Each red dot, which make up the shape of the ship, are shade white on their left side and each blue dot, which make up the clouds and sea, are shaded white on their right side. The opposing white dots trick the eye into seeing the ship move on the page.
