Just a very simple animation for the contest (100% pen! Only 3 scripts!) Since this uses the pen for the animation, I actually put one extra feature that only appears when you press space (Press space again to hide the feature). The feature is a slider you can use to change the size of the cubes! I am hiding the feature by default because animations usually DON'T have user interaction, but you can try it out for the full experience.
This is my entry to the above contest, held by @FriendshipScratch
