Fluid Functionalism

Fluid Functionalism is an open-source component set by designer Micka Touillaud, built on the idea that motion should explain something, like list items merging their backgrounds to show they belong together. Hover works as a preview, with the nearest interactive element highlighting as the cursor approaches, and every animation uses interruptible springs with fast, moderate and slow presets instead of fixed durations. Its components, from command menus to thinking indicators, suit app interfaces and AI chat products.
