Restructuring the first half;

* cleaning up the mess (p. 9 motion moved to "motion bank" to be reworked on pp. 10-11);
* contrasting motion to the muted glissandi on p.8 (to continue in combinations with emerging noise on pp. 9-11);
* rhythmic behaviors on pp. 14-15; need part-wise development accounting for human imprecision;
* most of the material in the "motion bank" is rhythmically understated, and needs better articulation to work well across groups.
