At first I wasn't aware of the exact approach as Andy Warhol by stacking boxes. So I was trying to use audio softwares to make sound overlaps to produce the effect of that piece I mentioned above. However, simply putting sounds together, even if I edit them carefully, is probably going to give out a sense of humor and make everybody laugh instead of creating a sense of art. Then I tried to use images, but I'm not sensitive enough to choose images and combines them into artistic pieces with the same effect as Warhol's boxes, so I reject that approach too. Finally, when it came the 3:00 a.m. in the morning, I suddenly realized that I can mimic the way Warhol produced his box piece to show my passion. So I got up and pull out all of my video game boxes and came up with a plan to build them up (details are in the next section).
