Side notes:
-I expected to spend a week on this project, but in true Computer Science fashion, it took three weeks (50 hours). Figures...
-1 day was spent drawing and adjusting the spinner animation.
-1 day was spent writing the tutorial
-The "correct answer" sounds are my voice. I couldn't find a satisfying correct "ping".
-Near the end of the project I had to completely rewrite my question-asking algorithm because it couldn't randomly ask every possible question exactly once. Not a pleasant experience...
-3 days were spent adding and tweaking interface elements.
