Hi. Thanks for giving us all the opportunity to create a Thumbnail for you. It's a great idea. I decided to make an animated gif for my entry.
SNDBOX THUMBNAIL COMPETITION | My entry And A Breakdown Of How I Animated It
It was a lot of fun to make. My entry post linked above includes the full size gif and I've also given a rundown of how it was made. Hope you like :)
Thanks again
