A rendering of the opening title of Stranger Things entirely in SVG. It uses a filter-generated texture to create the patchy luminance across the logo. Then it adds a highlight blur whose opacity is boosted with a ComponentTransfer. Then SMIL is added to vary the opacity boost to create the effect of a glitchy neon sign.
Inspired by MIchael Edelstone's CSS/HTML version (whose font CSS this still uses.)
