Hologram Projection materialises your word as a light field rather than an object: it fades up through scan lines, the colour channels drift apart and snap back, and the whole projection keeps flickering as if the emitter is working hard to hold it.
Six keyframes run simultaneously rather than in sequence — holoAppear, scanPulse, flicker, glitchShift and two chroma shifts on opposite channels. Running them concurrently at different periods is what makes the projection feel unstable instead of animated; a feColorMatrix/feGaussianBlur/feMerge chain gives the light its bloom.
Export WebM for a genuine alpha channel — the scan lines and flicker composite far better over video than a version with a baked black background.
