I had an idea yesterday for a ToDo list that gives you a random task or activity to do when you shake it, and weights the results by your current mood. Users will be able to set parameters when they new tasks by setting sliders like "need to do vs want to do", "thinking vs acting", "productive vs relaxing". Set info on location, timeframe, deadline, flexibility of deadline, dependency on other tasks, etc. Setting the sliders to reflect your current mood and then shaking your phone will give you a random activity to do, optimized for your current circumstances.
This also gives me an opportunity to work with sensors and databases, which I haven't done up to this point. I've got a couple of other ideas, but I already started working on this one, so hopefully I'll be able to use the TaskShaker to figure out what to work on after I finish it!
