Try out this logical game http://scratch.mit.edu/projects/deerel/283053
It's based on idea that I used on my previous job to showcase multi-agent behaviour - smurfs move automatically by certain rules, you may only control one thing, but through it you control all of them because their behaviour depends of actions of others.
Also, you can take the game and remix it to create another levels... I did a programming work, maybe it's your turn to create superb levels :-)
