A Twitter reply chain that began with a Tweet by broonoart stating "I swear u can add those genga colors to any drawing n it'll look raw asf." The statement was followed up with a drawing of the shocked black guy meme in the style of a genga production art.
The drawing then spawned an ongoing reply chain, as professional animators from the anime industry compounded upon broonoart's initial illustration, essentially going through all of the steps of keyframe production.
