This workshop, led by visual artist Antonio Roberts https://hellocatfood.com/ aka hellocatfood, will introduce you to the basics of Hydra, focusing on how image sources can be transformed, modulated, and composited by chaining together different functions.

By the end of the workshop you will learn the skills needed to perform using Hydra. If you've ever been curious about using code to make visuals and have aspirations to perform at live coding events and Algoraves then this workshop is perfect for you.
