// Project 06 - Duck Clock 

    //Concept: grid of 5 x 5, 24 ducks, every hour a new duck swims onto screen. 
    //each duck rotates once a minute.
    //need a function to draw the ducks
    //need a loop for the ducks- where do they enter from, where do they go each hour
    //need a transformation to roate each duck around its center axis- part of function
// b for bubbles in water:
var b = [];

var angleR = 0;
