Once you get it, it certainly does give off a strong message, aside from what is evident.

This poster is a variation on other illusions (if you look carefully you can see the alternating black and white back-lettering), which are commonly found in Kitaoka's designs. Since motion is perceived in a dark-to-light direction, our periphery is tricked as we look over the image its luminance changes.

I really love how this poster was used to create a powerful message. I am really curious to see how else this periphery drift effect could be used in real-life applications.
