Thingsapp is a project mainly written in Python, it's free.
Python bindings for accessing Things.app
CulturedCode's Things is a Mac-only product. I don't want to carry the macbook to home, and want my Things tasks accessible from anywhere. Therefore I want this project to provide me, at minimum, a tool to dump Things tasks to Dropbox and, at best, run a web application that will allow me to manipulate Things from anywhere.
It is far from being done, though.
