Since I was a child I was fascinated by fluorescence, phosphorescence and bioluminescence. Seing the movie Avatar was the cherry on top that motivated me to make some of my own decorations.

Some time ago I discovered what UV painting is and decided to try it out. A few Artists I found also tried to merge daylight painting with UV painting. Meaning that by day you see a normal painting, and if the room goes dark, and uv light is on, the painting looks just like a scene from Avatar by night, glowing, shining, … and suddenly I wanted to make this a hobby of my own.
