Lately I’ve been working to learn my way around Processing, a free open-souce visual programming language. There’s a lot of great documentation and people always adding new libraries to it that do a lot of the heavy lifting for complex functions.

Also, a lot of people post their code online, so if you want to learn how to use a particular function you can see what someone else did and copy/paste the useful parts into your own sketches.

Here’s a few videos created by other folks doing some pretty awesome audio-reactive generative imagery:
