What Hacker News says
5 sourcesA little bit of background on Effeckt: The idea is we need reusable transitions and animations [0], all classy but most importantly they must perform well on mobile. The project is still very much a WIP, and as some comments below indicate, there are still janky interactions that are unacceptable. We're looking at integrating something like Topcoat's Benchmark server [1] to have CI setup for CSS performance regression testing. Identify and improve (or cull) any effects that are inappropriately slow.
The project started over on lazyweb-requests [2] and Chris Coyier has led development of the project from early on. It's a very open and community-driven project, so there are plenty of opportunities for everyone to get involved and move things. Lastly, the readme [3] helps explain a lot of the goals and ideas of the project.
