We chose to use a phone case because we had to find something in common to work on. We both have phones and cases on our phones so we decided to use the lights on the case. We wanted it to look cool so we used a lot of lights and colors. Everyone like phone cases but they are usually plain and boring. We thought lights would make it look less boring. A phone case is important to us because phones are important to our life. We would always be bored without phones. Without a case your phone can break and we won't be able to use it.
