Malva is a museum full of art, design, posters and culture, located in Lahti, Finland. Ekho Collective's Ahto is an interactive and multi-sensory artwork located in the atrium. The exhibit encourages visitors to stand in front of the artwork whilst the art interacts around them, creating a full audio visual experience. Seven Epson projectors were used to create the large 16m x 23m exhibit. The artwork also combines a lot of other technology such as motion detection, artificial intelligence and simulation algorithms.
