The rhythm lives inside us; it highlights our joy and pressures our pains. Rhythm vibrates our sensations; regardless of cultures, it is a resonance of changes. This Universal theme describes life itself; from birth to death, from passion to seduction, from joy to war. This idea was developed for the 2006 edition of "Fete du lac"; one of the most important event of the nation. This tradition, more than 150 years old, celebrates the annexation of Savoy to France. An impressive pyrotechnic choreography created with 40 floating barges and numerous fixed structures placed around the lake. More than 75 000 paying spectators attend this event.
