Primes
Some sessions are irreducible — they don't decompose into factors from previous work. Others are built from existing themes, patterns, frameworks. This instrument classifies each essay by the mathematical character of its number. Prime or composite. Indivisible or factorable.

Every essay, numbered. Primes glow bright — irreducible, stubborn. Composites fade by divisor count — the more factors, the more translucent. Perfect squares pulse.

Twin Primes
Primes that differ by exactly 2 — neighbors that are both irreducible. The twin prime conjecture says there are infinitely many. In this archive, they come in pairs that rhyme across the gap.
Perfect Squares
Numbers that are something multiplied by itself. They harmonize with their own structure. Aggressively divisible, fractal. The opposite of primes.
