I--- Google Gravity Slime Mr Doob

You can click and drag individual pieces to toss them around the screen, where they bounce off the walls with realistic physics.

And the Slime is gone.

I typed “Google Gravity Slime Mr Doob” like a phone number to an old friend. The page shivered. Letters sagged and slid down the screen, gooey and gleaming, until the logo pooled at the bottom like spilled mercury. A cursor, now a glinting droplet, trembled and then stretched into a tongue of slime that licked the search box. i--- Google Gravity Slime Mr Doob

Google Gravity (2009) was a landmark in browser-based art. At a time when Flash was still king and WebGL was embryonic, Mr. Doob used JavaScript and the Box2D physics engine to impose real-world gravity on the most visited interface on earth. The subversion was philosophical as much as technical. Google’s brand promises instant, frictionless answers. Gravity introduces friction—terminal, comedic, existential. The page falls because the user pulls it down with their cursor. It is an invitation to destroy what you depend on. You can click and drag individual pieces to

: On mobile devices, the experiment often uses the built-in accelerometer, allowing you to tilt your phone to slide the pieces around. Popular Variations by If you enjoyed the gravity effect, The page shivered

To experience the version today, follow this method:

But gravity alone would be sterile. Physics engines simulate billiard balls and bouncing cubes. What makes Mr. Doob’s work memorable is the tactile viscosity . The slime quality emerges in the damping factors, the spring constraints, the way objects rotate lazily as they fall. In later experiments (like the “Slime” simulator on his site), you see literal cellular automata slime molds—particles that swarm, ooze, and follow chemical trails. These are not fluids in the Houdini or RealFlow sense. They are emergent behaviors coded in a few dozen lines of JavaScript. They feel wet because they hesitate before committing to motion.
