One of ~200 videos I directed while serving as Director of Animation at Flocabulary, 2014 to 2019.
This was one of the quickest videos we ever made. We cranked it out assembly line-style, with me writing the shot list and storyboarding, and Eleni (our art intern at the time) illustrating each scene as I finished it. I then edited and (lightly) animated her illustrations, and that was that. The video was done in a day. It's no frills, but how fitting? A simple video for simple machines. 
Make sure you stick around for the death-by-pterodactyl scene. It's one of my career highlights. 

Directed, Animated & Edited by Drew Roberts
