I don’t know what it is about this animation, but it resonates some fundamental piece of me and the first couple of times I saw it I literally teared up. But that’s me getting emotional about shapes and sounds, which even I don’t understand so yeah. Thanks goes to Daps for unwittingly introducing this to me several years ago.
Caustics are those lines that light traces at the bottom of your teacup.
not exactly a circle, but still pretty cool.
Light is neat!
The immiscibility of oil and water creates a multitude of bubbles of all sizes. A lack of miscibility occurs when the forces between like molecules are very strong for two liquids—essentially the oil molecules and the water molecules are so much more strongly attracted to themselves than they are to one another that they cannot mix. Surface tension—another expression of molecular forces—pulls the oil into droplets that float in the water and refract the light in such lovely ways.
