projection

Statement

A placeholder sketch. A latitude–longitude sphere is projected from its pole onto the plane, the way a stereographic projection maps a globe: lines near the pole run off toward infinity. The tilt changes with the date.

仮のスケッチ。緯線と経線を引いた球を、極から平面へ立体射影しています。極に近い線ほど無限遠へ伸びていきます。傾きは日付によって変わります。

What you see

Thin black lines on white: a sphere's meridians and parallels, stereographically projected so that they form nested circles near the center and sweeping arcs that leave the frame. The sphere slowly turns.
