Matt Perry is the creator of some of the most widely used web motion libraries in the world. His work has transformed how developers bring interactivity and smooth animations to the web.

For the last six years, Matt was at Framer building Framer Motion. He's now taken it independent as a new project called simply Motion. If you've listened to this podcast before, you know my main passions are software design and motion—and if there was ever a guest who encapsulates all three, it's Matt.

This is a technical but accessible interview about what makes the web work when it comes to motion. Whether you're a motion designer or an engineer, there's something here for you.
