Jolt Physics: https://github.com/jrouwe/JoltPhysics
What does this have to do with Jolt, the Clojure compiler other than in name? Is there a port to Clojure or other connection?
I think the name being the same is worth bringing up. Ideally you would avoid name collisions with big projects but admittedly it does happen all the time.
There are other collisions, like Jolt computer, Dr Dobbs Jolt awards.
However to be fair, none of it came to mind when I saw the title.
