<h3>Spinning prism</h3>
|

<p>
|
||||
<code>--gradient-10</code> is a conic rainbow sweep — originally designed
|
||||
for color wheels. Applied to an organic shape and spun at 4 seconds per
|
||||
revolution, it becomes something else entirely. The color order is preserved,
|
||||
the edge is alive.

desynchronization.

Three concentric blobs from <code>--gradient-13</code> (a deep purple-to-coral

ASW's <code>--gray-hue</code> cascades through all surfaces. The same blob,
|
||||
the same gradient formula — only the hue angle changes. The oklch color space
|
||||
keeps perceptual lightness constant across hues, so red and blue land at the
|
||||
same visual weight.

<h3>Waveform</h3>
|

<p>
|
||||
Twelve bars, each a different height and animation phase. The bounce keyframe
|
||||
is a squish-ease: it overshoots slightly at peak and returns. The stagger
|
||||
is 200ms between each bar — enough to create a wave motion, not enough to
|
||||
look sequential. It reads as a signal, not a list.

||||
