I’ve used this library myself on some interesting projects - having multiple layers of elements drift around screen based on mouse movements or creating complex animations on banners. It’s very powerful and there’s a bit of a learning curve but it’s very useful and I can recommend it.
This is a powerful animation framework you can use to make your own complex, bespoke animations. Like GSAP, it provides tools for building up long sequences of complex animations, as well as fine control over every aspect of your animation.
I’m always on the look out for good examples of web animations and currently there’s no better place to start than CodePen. It’s a great place to see fun examples of animations, and even has articles and guides.
