Bouncing Ball 4

Today, I completed the bouncing ball down the stairs project. The shadows were not a requirement but I decided to see if I understand its concept. Obviously, I don't and there's much to learn.

On Wednesday, I had to hand in my primitives rendering. Not so well done, that's why it's not hosted up. Will do so when I feel it's good. For now it's more bouncing balls... boing... boing... boing...
