I just submitted my project:
It looks like this:
Before I started I didn't realize the "curl" of the rock in curling is a bit mysterious:
I also randomly found this amazing curling shot gif:
Anyway, I'm glad to have submitted something. I didn't find as much time & energy as I would have liked over the past two weeks. And a lot of details took longer than I thought. (I was playing a lot with the physics until I just resorted to some hacks.) But I think it was a good experience for me in terms of how I should pace myself for game jams, and what kind of projects I want to work on for any future game jams.
Also, I haven't had time to fully look at all the other dev logs here, but from what I've seen so far, your projects look awesome! I'm looking forward to the showcase.
