Brazil. The historic center of Belo Horizonte was transformed into a vibrant stage of light and creativity during the 2025 edition of the Festival of Light (Festa da Luz), one of Brazil's leading public art and technology festivals.
Highlights of the event included a large projection on the façade of the Museum of Arts and Crafts, made with three Christie Griffyn 4K50-RGB pure laser projectors supplied by ON.
In its fourth edition, the Festival of Light has established itself as an essential event in the cultural calendar of the state of Minas Gerais, in southeastern Brazil. Over four days, the event presented 13 light installations and 12 video mapping works in public spaces such as the Plaza de la Estación, the Santa Tereza Viaduct, Sapucaí Street and the Sulacap/Sulamérica building, an emblematic building in the city center.
This year's theme, urban cultures, paid tribute to hip-hop, graffiti, dance and other artistic expressions deeply linked to the identity of Belo Horizonte, with the participation of local, national and international artists.
In the Plaza de la Estación, ON was commissioned by the festival to project on the centenary Museum of Arts and Crafts. In collaboration with SSA Mapping, the company turned the 60-meter-wide façade into a living canvas that combined architecture, history, and contemporary street art.
The content, created by VJs selected for the festival, combined animations, graphic elements and light art integrated into the building's architecture. Using advanced blending and warping techniques, the ON team precisely adjusted the projections to the uneven surface of the façade. To achieve the show, three Christie Griffyn 4K50-RGB projectors were installed on towers in front of the building, at a projection distance of approximately 33 meters.
"We chose the Christie Griffyn 4K50-RGB because of its very high level of brightness, the purity of its RGB color reproduction and its reliability, essential factors when working on large facades in urban environments," explained Hugo Rodrigues, CEO of ON. "The performance was exceptional: the brightness provided a strong visual impact even in the heart of the city, while the color fidelity gave the content an intensity and richness that connected with the audience."
The projectors were controlled using the Resolume software, running on a multimedia server with four outputs. According to Rodrigues, the experience highlighted the importance of combining technical expertise with the right tools: "Thanks to the knowledge of our team and the capabilities of the Griffyn, we were able to adapt the content seamlessly to the irregularities of the building, creating a projection that became one of the main visual attractions of the festival."
He concluded that "We received very positive feedback from the organizers, the artists and the public. It was very gratifying for us to see how technology played such an important role in bringing art and heritage together, and creating a shared cultural experience for thousands of people."
