(Akash Malik, 704332974) I have done extra credit parts 1 and 2. ( i have instanced all the 8 cubes from one cubes date by applying translations and also drawn each cube using one triangle strip. I also shrink and grow the cubes periodically by 1.1 and 0.9 by using a cosine function for the component of the scale matrix. I also rotate the cubes by 6 degrees each frame ( because setInterval (render,1000/60) renders at 60 fps, and 6 degrees each frame * 60 = 360 degrees = 1 rotation per sec = 60 rotations per minute.)) (you can look in the render() function for details)
