Make Casual Games Together: Monthly Game Project Concept

I’d like to work on some casual side projects with people and I was thinking of a format.
Would anyone else like to work on simple projects as a large community effort?

The concept would be that we would vote on a project that can be developed in a 1 month timeframe.
After voting is concluded the project is created in a public repository and anyone can download the progress and contribute.

There would need to be administrators to handle aspect like merging the project contributions, but I think this would be a good opportunity to develop educational material, as well as for community members to show off and have fun.

Could be anything from fun 2d games, AI experiments, graphic showcases.
Vote on interesting projects.

I think it’d would be fun to be involved in, anyone else think they would enjoy something like this?
