I started by asking people to draw me either a snack bag or a piece of potato chip on WeChat and Instagram. I used Photoshop to extract the main strokes in these drawings and put all the "chips" into each bags. The home page is supposed to be a potato chips vending machine. You can choose whichever bag you want and you will get a bag of chips while no matter which bag you choose, the chips in each bag are all the same.
