Grid Animation

I spent the day exploring Principle and made a couple of animations. Overall it seems pretty easy to use but there are a few things I tried that it doesn't seem suited for... or it may just be my lack of skills.

Since I've been spending a lot of time lately working on a new grid for our web experiences I thought it might be nice to make a simple animation to demonstrate the layout breaks.

I'd love to learn more about Principle and if any of you are experts I'd love to hear from you and ask you a few questions.
