// PENDULUM CATHEDRAL — the camera stands INSIDE a huge, slowly morphing
|
|
// harmonograph figure with real z-depth. Pattern taught: `p2` adds depth
|
|
// to the third pendulum axis so the figure becomes architecture; grow is
|
|
// OFF (the figure stands complete) and the drama comes from the 32-beat
|
|
// figure morph + a width swell that follows the bar like an organ.
