In the future, when technology is highly developed, capital will have many dark sides. I have visualized this dark mask. I created a scene of a sea of blood, in which a bunch of flowers grew. This is the embodiment of memory. The sea of blood is maintained by many sold brains, and when the sea of blood ebbs, scattered dollars can be seen from the ground. In this futuristic AR scene, memories can be preserved using advanced technology and sold for a price. This allows for convenient access to memories, and even the sharing of memories between individuals. The possibilities are endless, from preserving personal memories to accessing the memories of historical figures. This immersive AR experience offers a glimpse into the future of memory preservation, where technology allows for a new level of intimacy and understanding.
