The page showcases a cloud of “particles” that appear three-dimensional even though they are rendered on a flat 2-D \<canvas> element created entirely with CSS. Depth is faked through layered box-shadow, perspective transforms, blur filters, and parallax-style keyframe animation. As the user moves the pointer or taps the screen, subtle CSS transform: rotate3d() and translateZ() illusions make particles drift toward or away from the viewpoint, giving the sensation of floating in space.
The build weighs under 8 KB, is fully responsive, and demonstrates advanced modern CSS features—ideal material for teaching visual effects without JavaScript.
