What's the best way to detect lack of activity?
Let's say you want to Max to notify you if it has received no input for ten seconds. You could use a metro or a clocker to monitor activity constantly, and use a >= object to check when a time period 10,000 ms has been reached. However, by doing that, you're going to do lots of tests, only the last of which will give the looked-for result. There's an easier way.
