Kosada is developing Vuo, a next-generation visual programming environment. It will enable multimedia artists to create powerful real-time audiovisual projects, data visualizations, and apps — all without writing code.
With Vuo, non-programmers will be able to create their own multimedia software for interactive art and music performances, animations, visualizations, games, special effects, museum exhibits, kiosks and other artistic projects. Rather than writing code in a traditional computer language, the composer will drag and drop building blocks onto a canvas, connecting those blocks with cables to create the composition. Unlike most programming environments, artists will be able to interact with their Vuo compositions while they are running, allowing for live improvisation.
It’s a wonderful fact about the world that humans have thousands of living languages. And a wonderful fact about many software development environments that they provide ways to create versions of applications localized into the most common of those languages. But before localization (or should I say world-readiness) sweeps you off your feet, let me tell you about some unexpected difficulties with Kineme’s first localized application.
In case you’re not super minimal like we are and don’t already know, Richie Hawtin is the Berlincoolest musician ever. His label, M-NUS, is celebrating its 10th anniversary with, among other things, a blue lighted cube (pictured left). Ali Demirel, visualist for Richie Hawtin, includes Quartz Composer in his arsenal of interactive and realtime media tools, and has been using a couple of Kineme tools to control and interact with his visuals.
He used Particle Tools to get some interesting effects in the visuals displayed behind the musicians during their set. He modified the “Fire” sample to fit with the other visuals and the music.
He also used Kineme File Tools String with URL to access the information acquired by the Cube. Members had RFID chipcards, and it would get their name whenever anyone held up their RFID chipcard to it. Demirel then chose the right moment to display their name in the visuals.
For an interview with Mr. Demirel, including links to videos, check out the full story on Kosada.com.
QuartzCrystal is an offline renderer that turns Quartz Compositions into portable QuickTime movies. It supports 3rd party plugins, as well as patches that do not work in safe-mode-only environments (such as QuickTime Pro). It also supports software scene antialiasing, so if you have a Mac with plenty of RAM and a hard-core video card, you can make spectacularly beautiful renderings of your plugins, effects, and compositions.
Making pop-up menus in custom Quartz Composer patches is actually surprisingly easy.

- Set up a QCIndexPort input. QCIndexPorts provide values from 0 to whatever max you specify using
- (void)setMaxIndexValue:(unsigned int)max;.
Here’s a new version of the Xcode Template for Custom Quartz Composer Patches.
- Rebuilt from scratch – no longer depends on QCJP’s work – and, by extension, the Creative Commons “Attribution-NonCommercial-ShareAlike” license. My Xcode Template, as of version 0.2, is released into the Public Domain. You are free to use it for whatever – commercial or non-commercial.
- QCJP’s headers were replaced with headers assembled directly from the QuartzComposer framework – now located in the QuartzComposer/ folder of the project. I’ve exported a few more headers than QCJP had constructed, so there’s some added functionality (namely, image input/output ports).
- The project now automatically assigns an icon to the patch bundle, and installs it in /Library/Graphics/Patches/ for you each time you build, for faster edit-build-test workflow.
Please see the latest version.
See the old version’s blogpost for some additional instructions and user comments.

A few weeks ago I stumbled upon a P5 Glove listed on eBay for $20. It arrived a couple of days later, and I started playing with libp5glove by Jason McMullan, Tim Kreger, and Ross Bencina. I built a very simple Quartz Composer patch around it.
