I'd love to see this game ported to calculators.
www.addictinggames.com/kill-the-wabbits-game.html It would require a fairly robust physics system, but I think it's doable. Who thinks this is possible, and who wants to make it?!
By the way, I finished the entire game with the score of -5281. I think that scoring should be based on time rather than amount of shots fired, though maybe that's just me.
Edit: To clarify, I think Hard mode is what should be ported (easier on calc because of lack of mouse).
