Marvin

In case you just came upon this project and is wondering why Marvin, instead of a more SEO-friendly project name: Marvin is the Marvin from The Hitchhiker's Guide to the Galaxy. Go read it if you haven't already.

Contributing

This is initially an internal project at PicCollage. Recently we had some time to make an open-source version of it–but just enough time to make it so. This is the MVP, there are obviously much room for improvement. If you are intrigued or if you like Elixir or if you find any bugs (I guarantee you will), please fix it yourself (yup) AND/OR let us know!
