Not that I'm biased (!), but if you are able to roll your own, you can see two nice designs employing circle graphics at Grahame's site<http://www.sgitheach.org.uk/scope2.html> and at Oscilloclock.com . These are based on David's original design at cathodecorner.com . There are many other raster graphics based designs, which have kits available. Dutchtronix <http://www.dutchtronix.com/ScopeClock.htm> must surely be the most common, but a google will show more. Aaron
