Playing around with "open" or "active" icon states in the macOS dock in @rive_app. Thought I'd experiment on the @NotionHQ icon!

@drawsgood 🫡🤣

I apologize for this drawing in advance. 🫣

Boom! What a great demonstration of the @rive_app speed and performance, @gordonphayes!

[Gordon Hayes @gordonphayes]

Let's take a look at the performance of @rive_app animations using different renderers.

All running on @FlutterDev, release mode.

Skia: 9 tiles ~100ms (10fps)
Impeller: 9 tiles ~100ms (10fps)
Rive Renderer: 100 tiles ~16ms (60fps)

See this thread for info.

Check out this little educational interactive demo I've been working on with @rive_app . I have created it using vectors and raster images with meshes for the deformation of the numbers.

@rive_app A new era for Rive animation! Thank you, @guidorosso, @luigirosso and the rest of the team @rive_app that bright this feature to life! 😊🙏

@PedroAlpera @rive_app Like trying to press two like-poled Magnets to one another, @PedroAlpera 🤣

[Pedro Alpera @PedroAlpera]

You know went you try to unsubscribe from a service and is almost impossible?. This is an example of a button that cannot be clicked, made with @rive_app.
You can play with it, and see how it's made in this link: https://t.co/AhI5GYamFa

Thanks for the @duolingo shoutout, @reallynattu!

Thank You, Design Community ❤️

@PedroAlpera @rive_app I can't wait to see what you come up with (and you have rigged it), @PedroAlpera!

@LottieFiles @Spotify @googlephotos @Animagic_Studio @madebygoogle @gpeal8 @tiktok_us @YouTube @MKBHD @Twitter @TwitterDesign @Reddit @duolingo, the world's best learning app is also where you can find the best Lottie animations too. Over 270 Lottie animations, with a total of 22MB. @LottieFiles optimizer was able to reduce it to just 2.5MB (88% less)!

[Guido Rosso @guidorosso]

Duolingo is one of @rive_app’s early adopters.

@KurtHartfelder, in one of his first messages on our shared Slack channel, shared that his Rive test was 15x smaller than Lottie.

I'm so happy to finally be able to share this news! The future of Art and Animation @duolingo is looking even brighter. 😎

@joeyellis As a casual @Bengals fan, I concur.
