Here's my idea:
Basically a little toy that will have a series of cat nuns sing a Christmas carol.
I'm going to build it in Python because that's the language I'm most comfortable with.
I would like these cats to be able to meow out one, so if you're interested in recording yourself meow singing a christmas carol (in a .wav file format), or draw a cat dressed as a nun (in a gif file format), I would be thrilled to have your contribution.
Here's what I have after a couple hours of noodling around.
