show what I type in another window

Hi list,

I'm going to make a presentation about vim, and I'd like to make a live
demonstration of its functionality. Besides of typing and showing vim's
marvels, I'd like the audience to see in some way what I'm typing.

Do you know of any tool to do this? I Imagine such a tool as a
multiplier of the keyboard input, that receives my keyboard hits, sends
them to vim, and shows them (larger, with proper scrolling and timing)
in a separate window.

I think I can hack something like this with xdotool, and writing a
custom program that drives both xdotool and vim, but maybe you can
suggest an existing application for doing this.

Thanks all,
