Interactive shell for demonstration purposes

[Brian Quinlan]

Can anyone recommend a Python interactive shell for use in presentations?

Ideal characteristics (priority order):
o configurable font size
o full screen mode
o readline support
o syntax coloring

I've tried ipython but, since it runs inside a console window, and the 
console window has a limited number of selectable fonts, it doesn't 
work terribly well.

I've seen presentations using some sort of PyGame implemented shell. 
Does anyone have an information on that?

Cheers,
Brian
