Troupe

Motion design has a first-hour problem: every concept starts from the same references, so the directions converge. Troupe is a studio where a cast of persona-conditioned coding agents independently build a motion graphic from the same brief — eight genuinely different, renderable directions in about 90 seconds — then get scored blind. Eight agents each carry a Big Five-inspired record and a design kernel — type scale, color budget, easing, risk, and what they refuse to do. The prompt and sampling temperature are derived from that record. A code-owned direction grammar forces every agent to declare a layout, camera, and transition, and validates it. Outputs are self-contained HTML, sandboxed, offline, 1080×1080, eight-second loops. On Muse Spark 1.3, the core cast generated 8/8 in 2D, 3D, and Hybrid with zero render errors. The experiment reports the trade-off honestly: 2D is the most diverse (0.46 visual similarity), Hybrid is the most legible and the most homogeneous (0.62). A full eight-agent run costs about $0.01. Every run exports as a self-contained zip with a review page, the run record, every preview, and the vendored Three.js. Built solo during the hackathon.
