Wanted to share a blog post I wrote about live coding visuals with Hydra. It's not as well known as Processing for generative art or creative coding but it is actually really quick and easy to make really incredible beautiful visualizations. It also lets you collaborate live with other folks which is pretty awesome IMO. This post is an introduction that I tried to make approachable to anyone, regardless of your coding experience.
