Dedication

We would like to dedicate this book to those who started Etoys on the way to being an exciting and stimulating environment where children of all ages can create: Alan Kay, Scott Wallace, Dan Ingalls, Ted Kaehler, John Maloney, Andreas Raab.

We would like to thank Viewpoints Research Institute and the Office of Math, Science, and Technology Education (MSTE) at the University of Illinois Urbana-Champaign for their support of Etoys.

We would like to thank Google and Flossmanuals for making it possible for our group to meet and create this book.

Our deepest thanks goes to our community of developers, translaters, educators, supporters and teachers, who are the lifeblood of the ongoing journey of Etoys.
