This is a very cool animated optical illusion. I wanna explain to you first how the illusions are prepared and then I'll show the illusion.
這是壹個很酷的光學錯覺。我希望先向妳們解釋這個錯覺是怎麽準備出來的，然後再演示給妳們看。
When you look at it, is an image appeared to be bluring. But it's actually six frames of an animation. Now these frames are laid out in a specific way where each frame is cut into thin lines，and you can see those lines. and there's a specific space in between each one of these lines. And on this overlay, that same space , that same measurement between those spaces fits this overlay. You can see the black and white lines. And those match perfectly to the black and white spaces on these images.
當妳們看著它，會覺得是壹張似乎很模糊的圖片。但事實上，它是由壹個動畫的六禎圖像組成的。這壹幀禎圖像是以很特別的方式分布在這上面的，每壹幀被切割為很多細線，妳們可以看到這些線條。每條線之間有隔著特定的空間。然後在這張覆蓋膜上，相同的空間，空間之間相同的距離。妳們可以看到這些黑色和白色的線。它們和那張圖片上的黑白的空間是完全相符的。
So when you lay it over, you end up with one image basically, but as you move it, those spaces cycle between each of the six frames, creating movement
因此，當妳將它覆蓋上去，妳能得到壹張基本的圖案。但當妳移動覆蓋膜，這些空間就在六禎圖像中不斷轉換，也就形成了動畫。
