I think you told me that you were going to go with Scheme, but I wanted to throw another language out there for you: Inform 7. For one thing, the language itself is pretty fascinating–totally unlike earlier versions of Inform, if you’re familiar with them–and also, the author of the documentation, Graham Nelson, is a really good writer, which makes learning the language even more interesting.

Also, you can make text-based bee simulations with it.
