Final Project Idea(s?)

For my final project I'm thinking about completely taking more than one toy apart and trying to combine them so they interact together. If that doesn't work, I'll see what else I can do with the electronics. I don't suppose I'm in too much risk of electric shock with two double A batteries. I might fry a finger with the power from four AA's though.

I'm more curious to see what would happen than to trying to find a specific result.
