- Developer ShifroAnimation stress-tested Muse Spark 1.3 (xhigh) on 3D game logic in Three.js, producing a full browser open-world driving demo called Aura Valley.
- The demo features a 16 km² open world, a 4.2 km valley loop, day/night cycles, vehicle physics (top speed, 0–100 acceleration, grip, handbrake), autosteer cruise and free off-road driving, reportedly at 60 FPS.
- Scale founder Alexandr Wang reposted it as a "pretty cool 3D driving game," noting the result was well worth the time spent.
