I tried putting the original 5 event seismon screen up on nuc1 with the USGS page, but that MEDM takes up a lot of real estate and the arrival lights are hard to see from across the room (first attached image). You can't see the fonts either (and a lot of the locations are unreadable, we need all the language packages!), so I made a slightly more compact screen with big lights (second image, edit view is on the left, the running copy is on the right). The 3 square lights on the right of each block go from yellow (more than 2 minutes till arrival), to orange (between 1 & 2 minutes left) to red (less than a minute) for each wave type. While the arrival time is still positive, the rectangular light on the left will be orange for surface velocities between .5 & 1 micron, or red for more than 1 micron.

There's also a light at the bottom if the seismon system time gets more than 5 seconds behind H1:DAQ-DC0_GPS. We've found seismon dead a couple times, with the system time being stopped being the only symptom. I'd like to put this last test in DIAG_MAIN, too.
