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

I work at the intersection of design, technology and visual arts. I create images with code.

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

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

The HTML5 Canvas is currently my favourite technology for generative graphics projects. I am building a hub of curated Canvas resources focused on creative coding.
