Teresa on game design (inspired by a lesson on alive and not alive at school today, in which rocks and frogs were compared):
What if there was a game called rocks versus frogs?
If the frog sits on top of the rock and lays its eggs on it, and the eggs crack and the yolk gets all over the rock, then the frog wins.
If a tornado comes and blows the rock on top of the frog, the rock wins.
