Physics of Messenger Chatheads
I've searched long and hard about the physics and programming of messenger chathead/chatbubble but I couldn't find any resource that could show how the "physics" of the chathead works. I am talking about the way they compute the bouncyness of the chathead and computing the trajectory of the bubble, also the velocity according to the speed of the flick of the finger. I am going to risk it and post this question here in SO. Can anyone help me figure out the physics and programming behind it?...
