This year I finally did something that I’v been meaning to do for a couple of years now: I completed all Genuary prompts within the month of January.

Genuary is a creative coding challenge that happens every January. During this month participants follow daily prompts to create artworks using code. The challenge doesn’t specify which programming language (or any other software) participants should use, so I chose to complete the challenges using p5.js JavaScript library. I’ve seen many great designs created using this library and have been meaning to learn it for a while. This year I decided to persevere with the challenges, and I’m so happy I did! I learnt a lot about the library, different algorithms that can be used to create impressive generative art, and got inspired to continue working with it to develop my creative ideas.

This blog is a collection of all generative art pieces I created for Genuary 2025 using daily prompts. I plan to explore some of these visual ideas further in the coming months, so stay tuned for more posts about p5.js and how you can use it to create beautiful images. I also share my work on Bluesky.

Impossible day Try to do something that feels impossible for you to do. Maybe it is impossible. Maybe it’s too ambitious. Maybe it’s something you know nothing about how to accomplish
