It may be that there isn't a program that's both complex enough to make the problem visible and small enough to count as a demo. In that case, it might be better to call it a sample.
If it were my demo I'd focus on making the value visible. For example, if the value is correctness, then make it obvious when the state becomes incorrect. An incorrect program ought to hit this if it runs long enough.
