Fun DIY paper dragon that creates an optical illusion - Dragon Illusion

Today, I saw something very interesting on YouTube that uses 3D to create an optical illusion of a paper dragon. When you move your position, due to the visual effect, you will notice that the dragon's head seems to follow your gaze. Here, three different color templates are provided for netizens to download and print (download link). You just need to print them out, cut along the edges as indicated on the template, fold and glue them together, then place them on the table. Then, close one eye and use your other eye to focus on the dragon’s eyes while moving your body, and you'll witness an incredible phenomenon~ ^^

Actually, there are many optical illusion images on the internet that are quite fascinating. There has even been research into applying illusions in games, allowing computers to produce high-quality 3D visuals with minimal resources.

Here is a website that collects some interesting optical illusion resources:
