Develop of Bowling Game (HTML5, WebGL)

I want a bowling game in Javascript, WebGL, HTML5 I dont need the wholce concept with all rounds. Just one round with all pins and a ball. The user must throw the ball with help of mouse. The mouse must be grab ball and throw it towards the pins. The final result must be a little random so the same mouse move dont do strikes all time. Finally the experience in throwing the ball with mouse must be very near to real one. Source code must be clear and simple and easy to edit/manipulate.
