That's fair and I don't blame you for being suspicious of my testimonial. I built the widget that's used in the demo. My son didn't play with it until the entire demo lesson was complete. He liked the lesson and learned binary from it -- something we hadn't taught him elsewhere. He asked to do it again on another day. He then went on and did two of our other unreleased lessons on his own and enjoyed them. As a parent and as someone who helped build this, I was excited.
