Oh, just noticed that Winnie posted the same thing, before I did!
Sorry for the redundancy!
BTW - Jon (Winny);
I really liked your Transformer explanation text!!!
That is an excellent description - may I use it in the future?
When I try to explain how they work, the words coming out are just too dang confusing to the listening party(s) - resulting in the "Deer Caught In Headlights" stare.
(words coming out resemble that of the words found in Electrical Engineering Handbooks ["Standard Handbook for Electrical Engineers - version 14" is a good example]).
