Hi, i'm working on this tool called animachine which helps creating timeline based animations for React components.
It's packed in a chrome extension so you don't need to open your project in an other program to animate it with a rich GUI. (You can vote by ⭐-ing this gist)
Made with React and Redux
If you like this idea, i would be happy to talk about how it can fit in your component creating workflow at Reactive2015.
There is still a lot of thing to do about it but i hope i'll have time to get it in a good shape by the conference.
See you there in Bratislava!
