Notice how everyones face / hand is blurry? Looks like they are drawing on a plastic clear sheet.. or window infront of the camera which maybe reflects light like glow ink.
u can actually draw on the video frame by frame on video editing programs i made a lightsaber video for school
Thats exactly right...I did a lightsaber one too...editing those takes HOURS, which makes me think that the commercial using that stop motion, neon coloring style right now (sprint?) mustve taken weeks to complete.
Its either that or theres an instrument that i remember from music class that is related to the morocco (ironically, playing in the beat, too) that is a wooden block and a stick...makes the same noise, could be that.
