Since the moment I first encountered an “x” in school, I have been deeply moved and fascinated by mathematics, both as a method and as a phenomenon in itself. The beauty of graphs, curves, geometric figures captivated me. Later, I discovered number systems other than our decimal system. Binary: as if you have only two fingers. The iron rhythm resulting from this is evident when you align them vertically.

As a true nerd, I have other passions: programming and, for about fifteen years now, physical making. When I first saw the new drawing robot AxiDraw from what was then Evil Mad Scientist Laboratory (now Bantam Tools), I realized I could combine these three passions. I program binary patterns and have them drawn by the robot. Mathematics, programming, making.

Nowadays, I don’t limit myself to binary patterns alone but explore other number systems, other patterns, and ventures into the physical world and combinatorial problems. Always striving for completeness because anything less is unacceptable.

In my daily life, I used to work as a physics teacher for 28 years. Now I work with a fantastic team at the Ministry of Education to improve education on a national scale.

On these pages, you will find the plots I have created. You can purchase them if you wish. Send me a message, and we’ll arrange it. Even if you don’t have much money, we can sort it out via email.

#### Other Works

**Tone Generator Robot**: A robot attached to the frequency knob of a tone generator that rotates the knob to play recognizable tunes.

**Swagometer**: As a teacher, you want to know if your students have learned something. When I was a teacher, I created this measuring instrument. If the students liked the lesson, they press the green button; if not, the red one. At a certain threshold, the score is recorded.

**Chessboard with Rice**: A famous story in mathematics tells of a king who wanted to reward the inventor of chess. The inventor requested one grain of rice on the first square of the board, two on the second, four on the third, eight on the fourth, and so on, each time doubling the amount. This quickly escalates when you understand how exponential functions work. I illustrated this with a chessboard, real rice, and a depiction of the height of the final stacks of rice.
