Hologram Loader
A wireframe globe spins in a cone of light above a projector, with scanlines rolling through it and the odd glitch. Meridians are ellipses squeezed with scaleX, so there is no 3D transform at all.
Also known as: hologram projector animation, sci-fi globe loader, holographic globe.

}Customizing this loader
- Color: set
--ldr-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--ldr-size. Every dimension in the snippet is derived from it. Currently previewing64px. - Speed: change the duration on the
animationshorthand. Delays on the children are relative, so they keep their rhythm. - Accessibility: the root carries
role="status"and anaria-labelso screen readers announce the wait. The reduced-motion rule at the end slows the animation for users who asked for less motion.
