Re: Professor Pi character?

I think Professor Pi has a creepy looking knobbly head, but would be great as a margin marker for specific points in the documentation. As to the boy/girl characters, good idea, but care is needed to avoid gender stereotyping.

Re: Best first language choice

<r>Hmm. Start with flowcharts and a small instruction set; a pseudo machine language like CESIL (Google it). Then after the basics of flow control are more or less mastered, switch to something more advanced, say BASIC. That's how we did it in the '80s – why should it be any different now?<br/> <br/...
