In an attempt to do more web-based programming, I've made a litte application for making mind maps. The initial idea came from brainstorming about finding jobs as a programmer and being too lazy to use pen and paper! I've recently turned it into a Rails app with Facebook login support.
Still WIP, but you can try it here. It's hosted on a free Heroku account, so will take a while to wake up. More info on it here. Also on Github here.
