Happy new year, everyone! 
I spent the past two weeks mostly away from home and traveled a lot on trains. This meant a lot of time with my iPad, checking out new things, like trying to draw some virtual art and editing and scoring full videos on the device, which nowadays works incredibly well. I also finally “invested” in Auria Pro Cubasis 2, which feels like a true game changer in mobile DAW functionality.
Anyway, I was editing some videos and thought I’d like to add some crazy visuals. Naturally, I once again combed the App Store for audio visualizer apps that would accept inter-app or Audiobus audio, but this only ever led me to K-Machine, which I had never dared to dive into before. Not his time though! I downloaded it, watched a few videos, looked at the manual and like so often thought: “damn ... I wish I’d be better at math and coding”. Oh well. I then discovered vertexshaderart.com, which is made by Greggman, who also did the HTML5 Bytebeat editor, and which is compatible with K-Machine. There are only a few tutorial videos, but I still managed to have some fun coding up some colorful, moving squares, while listening to spacedog’s latest ambient jams:

3. www.vertexshaderart.com/art/YNrYu5vLMifYXQAyj
4. www.vertexshaderart.com/art/LhgDszKTstGZBHjt7
Those could also react to music and even IAA through K-Machine, but I haven’t really conquered coding this functionality yet. It’s only a line of code though and first tests seemed fruitful.
Of course, if you’re a good coder, you can get super crazy too:

So I hope to experiment with this further, which is fun, similarly to the Bytebeat coding, because once you understand the basics (really just four or five lines of code here), you can more or less randomly enter values and get decent results and still learn things while you’re at it.
Have you done something like this as well? Do you have other app recommendations? I heard Processing is a good language for generative art too and I might try it out as well.
