I need a tool that will take an input string and output a 'captcha'
image, for email addresses and so forth. Can anyone recommend one?

Sorry, I wasn't specific enough. I need one that runs as an executable
on my PC, not a PHP or ASP script.

A quick google would seem to imply there are many tools already available,
but their use depends on your environment. For example, it can be a simple
already-implemented .NET class if you're using ASP.NET, or a PHP script
invoking different image-generating back-ends depending on what you have
installed.
That said, I'd suggest http://recaptcha.net/ as an easy starting point.

Why would you need a captcha image for something other than an online app?
I.e., you need to clarify your requirements, including how "strong" you need
it to be.
If you just need text-in-an-image, both netpbm (aka pbmplus) and probably
imagemagick are portable programs that can do that.

Now *that* looks like one smart project.

Yes, except I saw someone half-seriously suggesting that when they run
across a recaptcha, they pick one of the words and use "penis". That way,
you have a 50-50 chance of actually getting that word into their database,
and if enough people are doing it, you'll have to word showing up at random
all thru the textbooks.
Seems to me the very need for captcha implies that there are significant
numbers of jerks out there who will screw with you just to be annoying.

I think a 50-50 chance of having to re-enter the captcha is enough to deter
but the most dedicted saboteur.

If their cross verification system works half decent, that's not going to be
a major issue.
To be effective, random words would have to be from a very small domain and
extremely well publicized. But that also makes it so much easier for the
site to redlist.

Fortunately, people are not simply jerks; they are selfish jerks. That makes
it so much easier to predict their behaviour and engineer around them.

I found one here that I like:
http://www.xtractpro.com/articles/CAPTCHA-Image-Generator.aspx
I even learned a little C# in order to get it to save PNGs to disc. :)
Of course I'll be learning a lot more C# once I get into 70-528 and 70-536.

That's a good point. I'm pretty sure it was proposed in jest anyway.
