I don't do posters very much, so I would like to use some existing templates. On the other hand, I want my workflows to be available for reuse, so whatever I use needs to be compatible with that.
To this end, I am looking for cases where both the package and the template for a decent poster are available under an open license (i.e. with no restrictions on the kinds of reuse). Ideally, there would be examples where that template has been used to create posters for scholarly conferences, and the poster's content were openly licensed too, but I can fill that gap.
Any pointers would be appreciated.
