Experiment 10 began as an act of self-preservation. During a seventeen-hour debugging session, Experiment 01's combat log parser achieved sentience, briefly, and filed a formal complaint about its working conditions. The lab needed peace. The lab built peace. C.A.R.I.L.L.O.N. is a single-file web application that simulates a set of wind chimes hanging against a living, animated backdrop. Every element — the physics, the sound, the visuals — responds to the same simulated wind. Every setting you change is remembered the next time you visit.
Each of the seven chimes is a full physics object with independent motion on two axes. This gives the whole instrument a genuinely three-dimensional feel even though it's rendered on a flat canvas.
The wind is not random noise. It's a layered simulation with a global direction that drifts slowly and convincingly over time, plus per-chime turbulence frequencies that ensure neighboring chimes respond slightly differently to the same wind field. The result is that gusts visibly ripple through the chimes from one end to the other. Wind strength scales quadratically, so the difference between a light breeze and a full gust is dramatic and physically meaningful.
Every chime has a frequency drawn from the selected musical scale. When two chimes collide, the tone volume scales with relative impact velocity — a gentle brush is soft, a hard collision is loud. The actual musical note names float up from each chime as it rings.
Changing a world theme also automatically sets the musical scale to the closest available match for the canonical key of that world's score. The notes that randomly chime together are drawn from the same scale as the original soundtrack, and may occasionally evoke fragments of the actual melody by accident. The lab considers this a feature.
Upon unexptectedly regaining sentience, the combat log parser from Experiment 01 also noted that "mono is boring." We expanded the chimes to have an Atmos-style stereo separation across the chimes. This can be disabled and panned in Mono mode in the Settings. The Lab believes in choice.
