Cassidy leaves a wonderful message for us on our canvas signature wall!

We had a few visitors at Nimble Collective this Friday. Cassidy Curtis and Alejandro Garcia!

Cassidy was my mentor at Dreamworks when I started working there. He was incredibly helpful and kind as I learned how to animate with the animation software EMO and their proprietary pipeline. Cassidy is now over at Google in the Spotlight Stories group where he gets to put his brain to incredible use doing all sorts of amazing things!

A few years back Cassidy and his lovely wife Raquel Coelho (animator, storyteller, bookmaker and associate professor at San Jose State University) made a very cute animation about how to make a baby. I believe this is based on a true story. At least, this is how my kids think babies are made.

Alejandro is also associated with San Jose State University, where he has been teaching physics for animators! In fact, a number of years back Alejandro took a sabbatical at Dreamworks where he came and consulted with me and Rex on Madagascar 3, Peabody and Sherman and numerous other projects. I loved having Alej explain the physics of how a dog could leap out of a flying “Boat of Ra” with a rope tied around his waist, grab a screaming child from another boat and maintain his momentum so he could swing under the original boat and flip both of them back inside safely. Yes, there were math equations and physics lessons. They were great!

Alej has a YouTube channel with all sorts of great videos where he talks about the physics of animation. He has also created an online course available through the Canvas Network titled Physics for Animators.

Here’s a quick video featuring Cassidy, Alejandro, and another amazing animator and actor Jason Spencer-Galsworthy discussing the physics of animation!

  1. Thanks Jason, it was great to see the impressive work you guys are doing at Nimble. If any of your creators need help with physics I’m happy to give them free feedback. And the equations are optional. 🙂

    Ha Ha! Yes, our short was based on a true story! It’s kind of unbelievable but that was how we made our spunky little girl Stella! Oh, and i’m glad you didn’t reveal Alejandro Garcia double identity as the super hero Green Ninja! Yes, the one from the world famous web series! it’s suppose to be a secret. so, hushhhhh don’t tell anyone. Thanks for posting! : )
