+
+Ornstein-Uhlenbeck brownian motion for TouchDesigner. A Script CHOP that generates smooth, mean-reverting procedural noise — perfect for organic camera drift, floating objects, generative motion, and anything that needs to feel alive.

+
+## What It Does
+
+Unlike random noise, Ornstein-Uhlenbeck motion always pulls back toward center — so you get natural, bounded wandering instead of unbounded drift. A critically-damped spring filter smooths the output for silky motion at any speed.
+
+- **Mean-reverting** — stays within your defined range, no runaway values
+- **Spring-smoothed** — critically-damped filtering removes jitter
+- **Per-axis control** — enable/disable X, Y, Z independently
+- **Deterministic** — set a seed for repeatable motion
+- **Sequencer-friendly** — all parameters are animatable
+
+## Parameters
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| **Speed** | Time-scale multiplier (0 = frozen) | `1.0` |
+| **Amplitude** | Output multiplier (0 = no motion) | `1.0` |
+| **Range Min / Max** | Output bounds | `-100` / `100` |
+| **Reversion** | Mean-reversion strength — higher = snappier return to center | `2.0` |
+| **Roughness** | Spring smoothing (0 = very smooth, 1 = raw noise) | `0.5` |
+| **Affect X / Y / Z** | Per-axis enable toggles | All on |
+| **Center** | Bias toward min or max of range | `0` |
+| **Seed** | Random seed (0 = non-deterministic) | `0` |
+| **Independent Axes** | Each axis gets its own noise stream | On |
+
