I think I have never yet done any work with the aim of symbolizing a particular idea, but the fact that a symbol is sometimes discovered or remarked upon is valuable for me because it makes it easier to accept the inexplicable nature of my hobbies, which constantly preoccupy me.

The things I want to express are so beautiful and pure.

My work is a game, a very serious game.

I try in my prints to testify that we live in a beautiful and orderly world, and not in a formless chaos, as it sometimes seems.
