I've had a go at the brain thing and I think it's a great improvement from VB.
One thing that I noticed is that while people similar to myself who have a grounding in electronics will understand logic circuits, those that do not will be a little confused how to put a brain together as there is no help file or tutorial as yet.
So I've enclosed this picture of what are called truth tables for the logic symbols AND, OR, and Exclusive-OR.
I hope this will be helpful to those who may need them.
All the best.
