I've just posted instructions for setting up a seismogram as a screen saver:

If you see any typos, let me know.

This can be expanded to include additional stations by adding wget 
lines to the batch file.

In fact, the image need not be a seismogram, but what could be better 
than a current seismogram???

Thanks,
John
