ballet

As our "dance* of the ball", ballet is an improvisational program [opus] that synthesizes walk categories from random coil.^~ Each ballet is a frame arrangement [lyrically, the bundling of two (2) or more fibors (either by encryption or decryption) into gameplay].In the Egglepple scenario, the 'dance' is stew choreography, and the band of dancers is yots. What I refer to as 'walking the string'. (see also Starbureiy ballet, groove (scheme), opera, #opéra-ballet, #libretto)
Note (+): We may consider ballet to be the transition from opening to endgame. I prefer to think of a ballet as an opera's lemma.
