HOW IT'S MADE

Neon Sign Flicker is made only of 2 glowing strokes: lines with a hot core and a soft glow traced along their shapes, with no particles at all. Techniques worth a look: keyframed parameters and post filters (bloom).

Every layer emits continuously and the 2.4 s loop closes seamlessly, so it can run for as long as you need. To recolour the line, select "Border tube" and change Core and Glow; Start and End set how much of it is drawn. The colour swatches by the downloads recolour every layer at once.
