We've already mentioned admin-on-rest in this blog. It's a frontend framework for building admin GUIs running in the browser, using REST services as backend, and powered by React.js and Material Design.
This open-source project was started about eight months ago, and it's approaching the first stable release. To showcase its features, we've built a live demo called "Posters Galore". It's the admin of a fictional Poster shop located somewhere in Neverland.
Here is a 2 minutes video exploring this demo:
If this makes you want to try the live demo, here is the link:
In addition to being gorgeous and fast, admin-on-rest is also very easy to learn and use. Check out the online documentation for details.
Note: The video may disappear one day because we didn't manage to buy the rights for the fabulous score by Wando. If you're the publisher, please contact us!
