In standard web design, elements are locked into a layout flow (block, inline, flex). Mr.Doob’s script strips these elements of their static positioning, converting them to absolute positions updated dozens of times per second by the physics engine loop. Why Did It Go Viral?

: Resizing or "shaking" the browser window causes the balls to bounce and react to the movement. How to access : You can play with it at Mr.doob's Ball Pool . Other Related Physics Toys by Mr.doob

As the web evolved, security protocols tightened. Google transitioned its entire infrastructure to secure HTTPS and altered the behavior of the "I'm Feeling Lucky" button to prevent automated redirects to third-party sites for security reasons. Additionally, Google frequently updated its homepage design, meaning Mr.Doob's snapshot of the classic Google interface became a time capsule of internet history.

Because Google has changed its search functionality and security protocols over the years, the original "I'm Feeling Lucky" shortcut may not always work directly from the main search engine. However, the project remains fully archived and playable. To experience it: Open your web browser.
