Grainy abstract backgrounds.

A little @codepen demo:

Enjoy!

Made a gallery of such gradient + effects blobs on @codepen
codepen.io/thebabydino/full/YP

Also includes an explanation of the how behind and interaction: the focal point of the `radialGradient` the blobs start from follows the cursor on hover.

Different blobs for light/ dark mode. 😼

Comparative screenshot of a few of the blobs in both light and dark mode.Demo screen with the info section. Each distorted blob starts out as a circle, tightly fit inside its parent svg element (which has its viewBox set so its 0,0 point is dead in the middle). This circle then gets a radialGradient fill. Choosing the SVG radial gradient over the CSS one as it also allows setting focal point coordinates (fx,fy) distinct from cx,cy - hover a blob to see how its focal point follows the cursor. <radialGradient id='g' gradientUnits='objectBoundingBox' fx='.35' fy='.65'> <stop stop-color='var(--c0)'/> <stop stop-color='var(--c1)' offset='.5'/> <stop stop-color='rgba(from var(--c1) r g b/ 0)' offset='1'/> </radialGradient> The circle with the gradient is then blurred, distorted & given a grainy/ dithered look. The last two actions make use of the same concept of altering the input using noise generated by feTurbulence as a displacement map. The displacement used for distortion is relative to input size. The noise used for dithering is finer (larger baseFrequency). <filter id='distort' primitiveUnits='objectBoundingBox' x='-50%' y='-50%' width='200%' height='200%'> <feTurbulence type='fractalNoise' baseFrequency='.00713'/> <feDisplacementMap in='SourceGraphic' scale='.3' yChannelSelector='R'/> </radialGradient> <filter id='grain' x='-50%' y='-50%' width='200%' height='200%'> <feTurbulence type='fractalNoise' baseFrequency='7.13'/> <feDisplacementMap in='SourceGraphic' scale='32' yChannelSelector='R'/> </radialGradient>

Grainy distorted gradient blob: 1 `radialGradient` (setting a focal point `fx,fy`) vs. multiple `radial-gradient()` layers (no option to control focal point).

Using filters for distortion & grain effect.
