Three ways a value travels to another value over time, and the way each one fails.
What to notice. In Gate, hit Toggle halfway through a slide — it reverses from
where it is, because the stored value is t and not a position. In Chase, drag the simulation rate:
the red dot's whole character changes with frame rate and the blue one does not. In Angle, drag the target
across ±180° and the red arrow takes the 340° route for a 20° turn.
