Recreating this fire effect

I am trying to find the fire effect for LED strip tutorial that ‘Rob’ used to modify to create the effect on his Falcon kit as seen in this video Rob's Bandai 1/72 Perfect Grade Millennium Falcon Model Kit Build - YouTube (8:55) mark.

I am a total newbie to Arduino and appreciate the help. Most of what I found started at one end and went toward the other end.

There is at least one example sketch called "Fire" or "Fire...something" that are included in the FastLED library package. It could well be one of those.

catboat: started at one end and went toward the other end.

Is that like saying "in one ear and out the other" ?
