COCOLAB Mexico was contracted to provide projection mapping on 3 sites in Oaxaca, Mexico on important archeological buildings. The Cathedral of Our Lady of the Assumption, the Plaza de la Danza, and the Santo Domingo Church all received custom created content following the traditional Guelaguetza Festival. VIOSO provided the system to allow for recalibration of up to 10 of the projectors in a matter of minutes prior to the show. Due to being archeological sites, permanent housings for the projectors and control was not possible. Therefore a specialized truck was deployed that housed all projection and COCOLAB had only a few minutes from dusk to darkness to calibrate the projectors.
