This is our second model built from the book 'The Unofficial LEGO MINDSTORMS NXT Inventor's Guide'. This book is an excellent reference for programming, building/designing techniques, etc. We highly recommend this book.
Completely built and programmed by my 8 year-old son.

Thanks, the book is great. And if I had the patience, the video would have shown the ball hitting the target (which it does quite frequently just not when it's being filmed)
