Aisol Caustics

Aisol Caustics is a background of moving light patterns like sunlight through water, drawn live on the GPU behind your section.

Six presets cover pool, ocean, dusk, studio, mono and mint, and the colours, speed, scale and softness can all be tuned in the panel.

It draws nothing while it is off screen or idle in a hidden tab, shows a still frame for reduced motion and the canvas, and falls back to a still water pattern without WebGL.

- Children slot: put your heading and buttons on top; the light stays behind them.

- Optional pointer glow bends the light near the cursor, only while the pointer is inside.

- Pairs with the free Ripple Dots and Silk Banner from the same studio.

What you control

• Preset, three colours and background

• Speed, scale, softness, brightness

• Pointer glow on or off and its strength

• Quality (render scale) for slower devices

• Content slot alignment

Limits: needs WebGL for the moving pattern (otherwise a matching still pattern is shown); the effect is a background, so keep text contrast in mind; a small Pause animation button sits in the bottom-right corner so visitors can stop the motion; one WebGL context per instance.
