Andy Balaam shows you how to write your first ever computer program on the Raspberry Pi ultra-cheap computer. This episode: we write the outline of our program, treating it like magic. We'll fill in the details later.. There are detailed notes at http://www.artificialworlds.net/blog/2012/11/14/my-first-raspberry-pi-game-part-03-its-like-a-magic-spell/

The book I mentioned is Structure and Interpretation of Computer Programs, available for free online here: http://mitpress.mit.edu/sicp/full-text/book/book.html
