What it does
An interactive toy that turns prime numbers into melodies. Generate a run of primes and map them to MIDI notes using one of several strategies — mirrored around middle C, onto the C major scale, as chords, spiralling up the keyboard, or with chord size set by factor count — then play the result on a mini piano.
