Talking Robot
A robot face built from 2D signed distance functions — rounded box head, circle eyes, animated pupils that blink, eyebrows that react to the talk parameter, and a mouth that morphs from a closed line to an open shape. An antenna ball glows on top. In VS2, map audio or MIDI to the talk parameter to make it speak.
