Random 4-Bit Lab

A small standalone HTML for generating random 4-bit states, watching their live trajectory, and exploring how bias and memory bend the stream.

Speed

160 ms / step

1-bias

50% chance each free bit becomes 1

Memory

18% pull toward previous bits

transitions

Bit locks

lock bit 1 lock bit 2 lock bit 3 lock bit 4

Locked bits keep their previous state, so the randomity can develop short structure.

Histogram of all 4-bit states

This version keeps things simple: random 4-bit generation, slight memory of the previous state, optional locked bits, and a live trajectory line. You can treat each 4-bit state as a tiny probe, a nibble, or a small random glyph.
