//Edit the next few lines to suit your page. Recommended values are:\
//numFlakes = 10; downSpeed = 0.01; lrFlakes = 10;\

var pictureWidth = 20;            //the width of the snowflakes\
var pictureHeight = 20;           //the height of the snowflakes\
var numFlakes = 10;               //the number of snowflakes\
var downSpeed = 0.01;             //the falling speed of snowflakes (portion of screen per 100 ms)\
var lrFlakes = 10;                //the speed that the snowflakes should swing from side to side\
                                  //relative to distance fallen (swing increases with fewer\
                                  //snowflakes to fill available space)\
