Ultraviolet Reality combines nature and technology by showcasing how the color and light properties of flowers impact their interaction with the environment. The series presents plants from two different perspectives: as seen by the human eye and in ultraviolet light, through pollinators eye. In normal light, flowers appear familiar and beautiful to us, but ultraviolet light reveals hidden patterns, signs, and attractive colors that help insects find the flowers and carry out their crucial role as pollinators.

The interactive section of Ultraviolet Reality allows adjusting the lighting to explore flowers from the pollinators' perspective by using different light spectra. This interactive experience encourages contemplation of human awareness and the limitations of our perception in understanding biodiversity.

Ultraviolet Reality challenges us to consider our responsibility for the well-being of our planet. It asks how we can contribute to the preservation of biodiversity. How can we establish a more sustainable and balanced relationship with our environment?

Kari Alonen is a long-standing visual artist from Central Finland who has become known both for his groundbreaking art and for the new combination of stone, glass, and light. Social criticality and humor are weapons with which Alonen takes a stand on the grievances he sees. "The guerrilla of humor beats the army of facts."
