I recently made All Change which is for checking your train times when changing trains.
This is to scratch a personal itch about trying to decide which train you are likely to connect with.
But most importantly, its a small, achievable project. It's only taken 2 days from first creating the repo to deploying to Heroku. This is in stark contrast to my usual tendancy to attempt large open-ended projects. So well done me for actually doing a thing.
