I was bored with the way all the famous to-do apps look, mostly mundane lists of things to do. Not inspiring. So I started tinkering my own vision of a better and more engaging interface: A world dark and set in the future, where planet Earth is under constant wave of meteors; human civilization has moved backwards and survives on farming and windmills for energy. The to-do items take the form of meteors falling from the sky. The best part is when a task is completed the meteor explodes into a giant ball of fireworks. A serious "bad ass" way to say task complete. On the other hand, if a deadline is missed, the meteor comes crashing with smoke and red flames everywhere.
