Greetings,

I'm wondering if it is possible to create a Manipulate that continuously
updates itself? More precisely, I'm working on a Manipulate that imports
and displays a severe storm weather map from NOAA
(http://www.weather.gov/) and then does some other calculations with the
background data. Putting aside the calculations for a moment, one method
for interacting with this data is to create a button that updates the
map when clicked. Another way would be to have the map update itself
regularly, say every x minutes, without any intervention from the user.
In this way the user is always seeing the most current map without the
need to click the button (note: The NOAA map updates on their web site
every 5 minutes, so this is not real time updating).

How might this be done in MathematicaMathematicaMathematicaMathematicaMathematicaMathematicaMathematicaMathematica? Is there some sort of timed EventHandler
that could be used?

Thanks,

Mark
