My first ever big exhibition, which was in Prague, was titled Artificial. I was toying with the words art and artificial. I don’t think I use my work as a form of therapy. There are people who disappear into their studios and spill their hearts out, but I tend to just think of something and then do it. Or is it just me filling up spare time rather than some internal need? If there is any internal pressure, it is likely to be anger.
