Just yell!
Thank you for my little brother and my mom's Iphone. There was this app that you have to yell to make something change colour and my brother was playing on it. So I wanted to make something like that on the computer for my little brother. Respect your siblings. Sometimes they can be annoying, but sometimes they can be very nice and lovable. Update: Added "TOO LOUD!!!" if there is a dangerous sound value.
