the 720
clock

--:--:--

A working clock in Dave's time. The red hand turns once every 24 hours; but a day is counted as half a lap, so the face only returns to its starting state after two days, 720°. The blue square flips at each 360°, showing which lap you are on: one turn is not enough to come home. The yellow hand shows ordinary minutes. The composition (primary forms and grid) is seeded.

LIT the local time from your device clock. MODEL the two-lap (720°) state is Dave's; it mirrors the spin-½ sign flip. ANALOGY Bauhaus composition. Self-check: hand angles are computed from the time and the lap parity flips exactly at 360°. ← SaPpH{{i}}on
