I constructed a long period seismograph for the Science Centre and 
Planetarium in Wollongong (Australia). It is sits on the exhibit floor 
under a plexiglass cover and successfully records earthquakes from the 
Asia Pacific region. It displays last 10 minutes, last 24 hours and last 
recorded event.

Its most important feature is that it not only is 'real time' but it 
also real. When significant events occur both press and TV visit and 
events can be 'replayed'.

BTW Jumping up and down in front of it has no effect at all due to its 
long period and various filtering that intentionally takes out visitor 
effects.
