That is a terrific service to the community. Many thanks. This will be a great thing for anyone who doesnt want to buy and restore a pattern generator just to set up and converge a set.
A few years ago I bought an avia disc.
http://www.ovationmultimedia.com/avia.html It was expensive for a dvd, about $44.00 I think. I just wanted a pattern generator, I didn't really need all the home theatre stuff. Also, the patterns on avia dont run as long as you might like them to.
