This is the online notebook of creative technologist Tomasz (Tomek) Zemla.

I work at the intersection of design, technology and visual arts.

I am fascinated by the possibilities offered by the generative arts & design. I create images with code. Most of the projects on this site are programs that algorithmically generate graphics.

You can find out more about my professional work on the About page.

What is in the name? Pixelbox is an imaginary sandbox of ideas where I get to play with colored pixels.
