2 squared: timer, notes, check. [alternate alignmentsizing: smaller, more traditional 'search icon' logic, but with handle pointing into ground twrd earth center; do away with 'latitude band' re-representations all together. way too distracting.] ALIGNMENT VARIATIONS (earthside) Polar air indicator (soft purple?)*(would create as fragment preface).. would tie into the co-rotating frame.. {{{if not, could align blue cold indicator with it? nix}}} Cold. Cool. Warm. Hot.. Aligned with outer edge cross section. Left side. Right side. {requires little into-page tilting, can represent truest Latitude variation..} Aligned with central earth axis. {might appear interesting, clear latitude depiction, the handles would be pointing straight "up"} Aligned with armiture. {the armiture would then have a purpose for being oriented that way.. could cue into textual labels for values. would require some tilting into the page to make the view windows 'drop' below the armiture into the atmosphere.} Are multiple instances distracting? what does all three/four look like? LAST Color cue the tanks relative to the color codes at left. There may be some "in-between" colors that are suggested by way of the parcel zone selects being in the middle of annuluses, and annuluses having an inner and outer extreme. Let this build the next page's temperature gradient and established color-standards for the in-between.
