Toggling that single Boolean triggers a full sequence: his fists clench first—as if he’s "loading" his arms like weapons—before the claws instantly pop out. Simultaneously, his eyes and mouth shift into a fierce, focused expression while his arms drop into an aggressive, combat-ready stance. On top of that, I wanted to showcase a practical UI/UX use-case (See video at 0:21): the proximity of the mouse cursor dynamically controls the timeline interpolation, making the interface feel completely alive and reactive, while devs just have to listen to a single 'clicked' event trigger from Rive.
