While attending a class for mobile app development a couple of months back, the day the teacher (T) unveiled the class project:
T: You must build an Android app. You can do whatever you want.
T: Don't overcomplicate though. For example, online servers won't be valued!
T: But don't make it too easy. For example, don't make a tic-tac-toe. That won't be valued!
T: And remember, you must use device sensors, like the camera, GPS, accelerometer ...
T: But don't just throw the sensor functionality if it doesn't make sense in the app you're building. That won't be valued either!
T: You have one week to think and send me a proposal.
Me: What the fuck do you want me to do then?
