Cornice is a cross-platform image viewer written in Python + wxPython + PIL. It doesn't pretend to be complete, fast, or even useful, but I like it. It has been inspired by the famous Windows-only ACDSee. Why did I write it? Well, because I like ACDSee, but it's not free and it doesn't run on Linux, which is my main platform. There already exists an ACDsee-like viewer, GTKSee, but it is unmaintained and it lacks some features I wanted (bookmarks, a good keyboard navigation and zooming).
