NOT FOUND is a Chrome add-on developed by kajiya.hiroki that offers a unique and immersive browsing experience. With NOT FOUND, users can share their browsing in real-time with someone else.

By simply starting up NOT FOUND, users can instantly begin sharing their browsing activities with others. The add-on allows users to overlay their mouse cursor on top of the cursor of the person they are sharing with. This enables them to share the scenery of websites through real-time screenshots and the URLs they are visiting.

One of the standout features of NOT FOUND is its ability to randomly record and save the mouse cursor movements of users. These recordings are stored on the server indefinitely. Then, at random intervals, the saved mouse cursor movements are resurrected on the browser. When users overlay their mouse cursor on top of the resurrected cursor, they are greeted with memories from the past, including website screenshots, which are inserted into the browser with added noise.

NOT FOUND is more than just a browser add-on; it is a work of Internet art. It offers a unique way to share and experience browsing in real-time, while also providing a nostalgic and immersive journey through past browsing memories.
