ferro toggle, made with claude opus 5.5

a ferrofluid dark mode switch that claude opus 5.5 made in one html file

try it live

people asked if this is really html only

it is. one index.html, about 64 kb, no libraries, no build step, nothing loaded from outside

the liquid is drawn by webgl 2 shaders on one canvas, and the sound is made in the browser too

controls

• click, drag or press space
• m mutes the sound
• add ?hq to the url for full resolution

run it

download index.html and open it in a browser with webgl 2

that's the whole install
