The Grafimathematica drawings are part of a serie drawings about optical illusions and weird fantasies."You have to admit what you don't know because you don't know what you don't know until someone tells you something you didn't know or you lean something new that you didn't know. So, what you didn't know by accident or by stumbling onto or learn about are all those things you didn't know anything about until one of these events actually happened. But then on the other hand, I know that I don't know. I just know what it is yet. But I will know as soon as it comes along to me. And if it doesn't then I'll never know. It's a mystery".
