The historic centre of Belo Horizonte was transformed into a stage of light and creativity during the 2025 edition of the Festival of Light (Festa da Luz), one of Brazil’s leading festivals of public art and technology.
Among the highlights of the event was a large-scale projection on the façade of the Museum of Arts and Trades (Museu de Artes e Ofícios), which used three Christie Griffyn 4K50-RGB laser projectors by ON.
Now in its fourth edition, the Festival of Light has become a fixture in the cultural calendar of Minas Gerais, a state in south-eastern Brazil. Over four days, the event presented 13 light installations and 12 projection mapping works across public spaces such as Station Square (Praça da Estação), Santa Tereza Viaduct (Viaduto Santa Tereza), Sapucaí Street (Rua Sapucaí), and the Sulacap/Sulamérica building, a historic landmark in the city centre. This year’s theme, “urban cultures”, celebrated hip-hop, graffiti, dance, and other artistic expressions rooted in Belo Horizonte’s identity, with contributions from local, national, and international artists.
For Station Square, ON was commissioned by the festival to project onto the century-old Museum of Arts and Trades. Working in partnership with SSA Mapping, ON turned the 60-metre-wide façade into a living canvas that blended architecture, history, and contemporary street art.
The content, designed by VJs selected for the festival, combined animations, graphic elements, and light art with the building’s architecture. Using advanced blending and warping techniques, ON’s team aligned the visuals precisely to the building’s irregular façade. To achieve this three Christie Griffyn 4K50-RGB projectors were installed on towers facing the building at a throw distance of approximately 33 metres.
