I would like to thank all the young - and not so young - people who have helped me to put this CD together. A big thank you to Antoine Nunes for the time and creativity he gave to make the game work. Thank you to Martin Guhl for his wonderful drawings.
A special thanks to Max (age 10) and Charlie (age 5) Gantet , Tamara (age 16) and Diana (age 14) Nunes, Julie (age 6.5) and David (age 3.5) Jakobowicz for all their helpful suggestions.
Thank you also to Caroline Lambein, Emmanuelle Gantet and Rosa Garcia Couto for all their work.
