The animation is divided into 2 parts.
① One is building & assembling LEGO; In the dark space, one lego part is blinking. And other LEGO classical parts are showing up like assembling. Then, LEGO technic parts are coming.
② Another part is sound-driven animation; I got coloration from 8-bit Mario game.
(+) Perspective problem is not my concern. I will make patterns by assigning color to each block.
