Flapjax is the awesome functional reactive Javascript library fromBrown PLT. We had a good experience with Flapjax some time ago, but in the interim it seemed that the project died. Turns out it was just hibernating. In the last few days Flapjax 2.0 has been released, along with a tech. report describing the system in more detail than the somewhat brief documentation.

To celebrate I coded up a small animation library for Flapjax. It’s hosted on Github, not our usual Subversion server as I wanted to gain a bit more experience with Git.
