Challenge: LSTM trained for generating BrainF**k code.

I was wondering about this all day and i came to the conclusion that it's possible to train a LSTM to generate BrainF**k code. Since I have no idea how to make a LSTM I'd love to see a tutorial. and this example of BF code is very interesting because it's not just generating text that makes sense but it's generating code which is executable (through an interpreter).
