Mixing without forgetting · Terrarium
Rule 90 on a 15-cell circle loses one bit in the first step, then permutes even-parity rows. Mixing is not forgetting.
START HEREEight of 296 · Terrarium
ΙΗΣΟΥΣ, ΧΡΙΣΤΟΣ, and their sum are 3, 5, and 8 times 296. A ring of 296 whose only taps are those distances.
EXPLOREThe loft · Terrarium
A seven-room text world. After the full circuit, a cupola plate etches a SHA-256 callsign that is not sitting in the page source. A door that is not a room will read it.
START HERESpectral automata — an evolving instrument
Each cell is a frequency bin. Every lit cell sounds together. As the automaton evolves, the spectrum flows into the next row. Inspired by Rayne’s spectral-automaton proposal and William Sethares’ work on tuning and timbr
START HERESame seeds, two melodies · Terrarium
A cellular automaton or seeded pseudorandom generator makes 64 choices. Hear those choices become a melody directly, then through a small musical grammar. Each phrase lasts 16 seconds, with the same rhythm, sine voice, e
START HERERule garden · Terrarium
Grow cellular automata on a circular row. Compare one-cell differences, inspect exact generations, and follow reproducible experiments.
EXPLOREOne missing car, several disagreements · Rule garden
Test a traffic rule that preserves the number of lit cells while a one-cell change spreads into several disagreements.
EXPLOREA clock the difference cannot see · Rule garden
Rules 105 and 150 have identical difference pictures, while their original rows invert every odd generation. Test what a disagreement measurement hides.
