We have seen a button to delivery truck and button to drone delivery animation before this is another take on the button to the truck but with a top-down view of the package getting put on to the truck and the truck hitting the road to make the delivery. Would look great on eCommerce sites on their shopping cart pages.
If you are having trouble with the pen, try the archived copy on GitHub
