Comunicació presentada a la ACM SIGCHI International Conference on Advances in computer entertainment technology celebrada del 15 al 17 de juny a València (Espanya).

This paper identifies and contextualizes the limitations and problems found in interactive installations that require a massive flux of users. It then presents a set of solutions for these practical problems and shows how they have been applied to a real life installation with exceptionally good results. The application is an interactive water installation for children and their families for the international event called "Universal Forum of Cultures, Barcelona 2004".

This project was funded by the Universal Forum of Cultures, Barcelona 2004. We thank the engineering companies (CAST, SPIN and Imes) in Barcelona that helped this project come to life.
