If you want to do something fun, plot your variance or offset using gnuplot.
Do it for a day. Then, take a small cooler like you would you for a six-pack
of soda cans. Throw your pi inside the cooler and then close the lid. Now
run it for a day and plot the offset/variance.
I've thought about doing a project that would provide a nice Web interface
overtop of things. Setup cron jobs to plot the variance, show the status,
and all from a web UI.

George,
I've been plotting offset for a number of servers for some time:
http://www.satsignal.eu/mrtg/performance_ntp.php
RasPi-1 and RasPi-4 are in an unheated cupboard and are reasonably flat,
whereas RasP-7 and 11..14 are in heated rooms, and the switch-on at ~04:30
UTC of the central heating is easily visible. Enjoy your plots!
Temperature for these devices has more effect than the number of satellites
used.
Cheers,
David
